Hi All,
My r/r quarter on my 86.5 was crushed in at work by our parts truck. Since I will now get a free quarter panel, I've decided to replace both sides with GTS quarters. (I also have a GTS rear bumper cover & associated parts to change over) Are there any necessary changes that have to be made to install the new quarters? I know about the rear cover mods. I'm concerned about the quarter mods.
Thanks, Hammer

You know they're not bolt on quarters, right? Lots of cutting and welding is the main necessary change. I think the gas door is different too.

The rear bulkhead (behind the tool kit)that is welded to both 1/4 is much different on the S-4 / GTs that is the big deal when fitting a late cover to an early car. The gas lid is much different nearly impossible to find used. Doing such a conversion is a lot of welding ,cutting and fitting.

Louis is also making a set of rear EXTRA wide panels....I have seen one and they are nice. Great work Louis!

Anyone make a front about 2 inches wider?

With all due respect let me say this. I was a mechanic for 30 years. I have worked in restoration shops. I worked in a shop for 5 years that built 911 racecars. I have restored or built a least a dozen domestic race cars of my own. I fabricate parts & sell them locally. I own a garage with a welder & a plasma cutter. My son is a certified body & metal man. I have done far more difficult modifications than this.
I have accumulated all of the parts to change this over during the last two years, including the fuel door. I have worked in adealership parts dept. for the last 6 years.
Everyone keeps saying don't upgrade your car, sell it & buy a newer one. I don't want to! I have owned my car since 1988. I have driven it all over this country & Canada & it has never let me down. I am attached to my 928 & intend to keep it. Hence my upgrade. I like to work on cars! I am confident that I can do this changeover. I am aware that there is "cutting & welding". I can cut & weld. I merely asked what kind of mods should I expect when doing this project. Telling me it's a PITA is not what I asked to know. You guys on this list have considerably more experience with working on 928's than I do, that is why I ask you before proceeding. Despite the experience that I have, I'd have to be a fool not to ask someone with more experience than myself.
That being said, I respectfully ask anyoneone if you can tell me what are the necessary changes to be made to effect installing the GTS quarters & rear cover on my car.
Thanks again, Hammer

Hammer,

Just noticed you're in the same town as I live and work.
I never did put Conshy under my avatar, as I didn't think anyone else would know where it is.
If you see a fairly beat up Guards Red 944 in the area....it's probably me.
I might have to hit you up sometime for recomendations for a good body guy.

Hammer you will need to cut out much of the existing rear bulkhead to create room to fit the taillights which sit higher and more to the front. The customers I have had who updated used the back few inches of a S-4 rear clip rather than fabricating new boxes to close the holes you must cut in the rear of the quarters and the bulkhead. Book time for the rear panel r and r is like 14 hours , 1/4 panel r and r complete is like 24 hours per side ,simple removal and install of the rear bumper cover is 6 hours. So there is a quick 50 hours or so. You will have to splice and cut the taillight harness into the chassis harness . The foam used inside the B pillar behind the doors is flammable and toxic as I recall. Your exhaust needs to be routed straight out the back. The rear bumper reinforcement , collapsible shocks etc are all different. But the basic overall dimensions are the same. Pulling the rear 1/4 windows to access the spot rivets means you probably will need new 1/4 window seals especially if you are ditching the S spoiler.That would require new rear hatch mouldings as well. It is not a difficult job since nothing is bent like in a accident just a lot of time which it sounds like that is not an issue for you.

And i thought the gas door was going to be the only issue.

man, sounds like some real nice, GTS style flaring is in order. that may be the best way out of this, and then buy that GTS reflective strip and add it to the S4 cover.

otherwise, jim has pointed out a ton of time.

keep us posted!

Mark he has an 86 your 86 was already modified at the factory as a preproduction unit made to look like be an 87 so yours would be easier.

I think Dr Nick in the UK did this to his orange car. You might want to check with him if he doesn't chime in here.

I put an IFC kit on an early 928 a while back, mostly because of the tail light issue. The S4 gts tail lights are higher up than the early body style light. The IFC rear bumper cover sets the S4 lights in the early holes. Lower.

I too was going to weld on quarters, but decided to go FG in the end. It was really not that bad and looked great when I got though. I had to do a lot of blending though. The IFC quarters are pretty much the entire quarter. The entire car took about 3 months including body, paint, mechanical, interior and chasing electrical bugs etc.

As far as the Gas door, I opted to hammer one out of aluminum rather than buy a gts door and it worked fine.

Thats about all there is to it. Probably the hardest part for you will be opening up the holes for the tail lights using a stock bumper cover. The worst part of welding on these cars has to be that tenacious undercoating. Its a real smoker.

I also scrubbed the side markers. Got a complete set of JY S4 light connectors for the entire car.

Not sure if you are going to do the front, but I folded the stock fenders to fit the IFC front bumper cover and made custom air inlets rather than pay mucho $ for S4 fogs.

Dont know if this helps but...

Great, some info I can sink my teeth into!
Since our company parts truck crushed my qtr. while parked in the employee lot, the damage is covered by company insurance. The car will go to our restoration shop for repair. The r/s door was also damaged. I have a perfect S4 door to replace it. The deal I swung is this: They replace both quarter panels. I pay for parts on the left one, they the right. We use my replacement door rather than repair the current one. The saved money goes towards the l/qtr labor. They do NOT paint the car. That money also goes toward the left qtr. labor. I must do any 'extras' like fabbing up the boxes for the tailites in the rear body panel, & any other 'mods' that have to be done. It would help if I do those promptly so I don't hold up the shop techs. That's why I'm trying to get the details on the changeover. The way it worked out, I have to pay for the l/r qtr. panel & the undamaged upgrades (rear cover, beam, shocks, spoiler, rear S4 hatch, mouldings, & weatherstrips) which I have already. All the labor is on the company. My son will paint the car for free using our paint booth. He owes me about 5k for the fabrication & financial help I've done for his hot rod. So you see, that's why the custom details are important to me.
Is that foam also in the rear body panel? Would it be dangerous to use my plasma cutter to cut out the tailite holes? Must the outer wheel houses be changed to fit the wider GTS quarters?
Thanks Jim, for the response & the answers.

Where abouts dude? I grew up on W.11th. Now I live on W.4th.
Where do you work? I'm at Keystone Motors.
I'm the 'only' black 928 in town!
