I was bolting my seat (Recaro SRD that mounts to the stock holes) into the stock mounting holes, and somehow broke one of the clips that hold the wobble nuts that are in the boxed section of the floor. The nut sits under a small square plate that is welded in place. Anyone now how to fix this? I am planning on cutting the welds using a dremel so I can get to the nut. Anyone know if I can just get a new nut and clip install them and reweld the plate back on? Any feedback would be appreciated.

Thanks,

i drilled it out, through the floor boards and mounted the rails used 2 large washers, one inside on the floor and one outside underneath the car. worked perfect.

I did that too, but I have always worried that in a wreck the force might pull the bolt/washer through the sheet metal under the car and sheer the bolts off. Any thoughts?

yes, your seat belts are not attached to the seats, so shouldn't make a diff (if you wear seat belts). can't imagine the stock set-up is much better.

So you just used an extra long bolt and a nut on the bottom side? I thought of something like this but since that part is boxed it looks like you would have to use a pretty long bolt.

Manning

Yes, and double nut it on the outside.

I've heard of many different ways of fixing these seat anchors. I've seen some repairs I couldn't believe, or live with. Early cars seem to be especially prone to this. I know some have welded a nut on the bottom of a washer, and welded that flush into the frame. I repaired a couple on my avatar car using 16 gauge steel, bending/fitting, welding a peice of 3/8" flat stock on the bottom of the upper plate, nutplating the inside vertical flanges so I could fasten the peice to the vertical structure in the car, laying out the hole, drilling the 6mm threaded hole, re-installing it, and having it welded when I had the chance. Do a search on "seat anchor repair", and I think you'll get more info. I couldn't find any pics of what mine looked like after the nutplates, flat stock, or holes were drilled in it. I personally don't like the idea of going all the way thru the floorboard, but, to each their own ya know. Good luck!

Oh yea, the real kicker is...........I STILL haven't taken the car down to get those peices welded in the frame permanently yet. Its attached to the frame with just 4 10-32 screws going into nutplates mounted inside my fab parts. LOL God! I've GOT to buy a mig welder! Heres one more pic of what one peice looks like fitted, but without the screwhole, and nutplates.

Could you use a Time Sert to fix it?

Here's to bringing back ancient threads.

I've got the same problem on my '83. The thing is, the seats are already so bolster-less that I've decided to fix the mount itself when I put in new seats (probably Corbeau A4's, I sat in some and they are extremely comfortable for me, even at 6' 1").

For a while I was pretty worried about this, but I figure that the seatbelt will be my saving grace regardless (but getting hit from behind would not be desireable at this moment (it's the driver's side, front/outside mount)).

I just don't want to have to pull the carpet and learn how to weld, all in one day.

Yep,

Oh dear lord. I thought I had washers figured out for the most part.

Had this problem with my '84. Took it to my favourite body shop, they had the parts on the shelf to weld right in - square steel with a threaded insert. Seems this is a fairly common problem. Don't recall exactly, but seems like it was less than $100 to fix 2 of them
