Thanks Dave.

It at least means that we don't have info. Possibly that Porsche don't have info either. Maybe that many of those cars were never made. Its probably combination of all three possibilities. All we can do is to try to find missing data.

If someone would provide me with info regarding the following, I'd appreciate it: WP0JB2920LS860245

Rob Edwards

This car is 33 cars older than my '90 GT, which was born on 1/10/90. By any chance is there a 'born on' date on the VIN sticker in ther driver's side door jamb? I'd be interested to know the date.

WP0JB2920LS860245

C03- California
M28.42
A28.16
I400- Pressure cast wheels, I assume this means Design 90's....
M418- Protective side moldings
M474- Sport Shocks
I498- Without rear model designation
M570- Rear A/C
M650- Sunroof
I691- Alpine CD-2 CD player

Thanks, Rob. IIRC, the car was made in February of 1990. When I get the car back from the shop, I'll try to verify the exact date.

Thank you Rob!

Just saw this post for info was missed .....

Details on the sticker are accurate, but the option blacked out is M220, which is limited slip diff. I can't understand why someone would take an LSD out. It's worth physically checking to see if your car still has the LSD.

Thanks for the look up.

We have it off the ground and did the wheel spin, when we first got it up, just to check, no indication of an LSD, with this information I'll now have to look closer perhaps the clutches are worn out.

If there isn't an LSD it becomes even more intriguing. If the delete was done at the factory, you'd think they would have printed a new sticker, if the delete was done by a PO, they were very thorough to black out the code in the manual.

The sticker in the car is harder to read, but I'll check if it is blacked out as well.

Is there anything else that I can learn about the interior, it is somewhat different from the other 928s that I've seen either in person or in pictures.

Thanks again for the help.

So early '90 MY should be December 1989 or close to it. Definitelly long before February.

First thing to check under car is stamping under differential.

wpgshark

What specifically should I look for?

I've reviewed
https://rennlist.com/forums/928-foru...ited-slip.html

The only stamping I can find is on the bottom edge of the casing flange, right against the differential cover. On one side G2812 is stamped in, which is different from the G2813 that the VIN describes, on the other is 00507 which I assume is a serial number. It would be interesting to know the history of the tranny.

Reviewed some more, went under with a copper brush and raised a 1 K right in the middle, if what I've read is correct that means the car has an open dif.

thanks,

Lance

G2812 1K 00507 is 7th manual gearbox made for '89 MY.

Hilton

His VIN is this:

WP0JB0921JS860336

Interesting that the transmission is a K-year one ('89). Factory swap? Early warranty work?

Dave928S

... or maybe the original owner didn't like the characteristics of an LSD when driving in wet/snowy conditions and asked them to take it out ... although you would think they would just swap the spool if that was the case. Warranty work you would think they would just replace parts/the whole box and leave it LSD. It'd be interesting to the get the story from the original owner.
