Also looked at the subs, but they are a casting without any numbers on them.. At www.mittelmotor.de you can however chase down most all numbers for original porsche parts in their catalog and order them at the same time if you feel like it ;-)

Thanks for that. I used the www.autoatlanta.com website to confirm the part #, but the local dealer believes the swap will not work.

No issues though ... used G64 front diffs are going for ~$200 on EBay, going to try another local source first.

Good luck with the swap !

Exactly! Shipping it overseas would not be cost effective for such a part.

I am still looking for the correct new (longer) bolts I need for the swap over of the ring gear. Its a M12 x1.25 bolt in 12.9 grade, but would be nice to have the part number. Mittelmotor don't list inner diff parts. I'll look at auto-atlanta in return

If I'm looking for Porsche part numbers I just go to the Porsche online PET rather than via a 3rd party.

I had an issue accessing the 996GT3 catalogue but the 996 catalogue list two possible options for the ring gear bolts (with LSD).

999 217 152 01 or 996 332 276 00 depending on which diff (can't quite read the full number in your photos).

The GT2 catalogue lists the 999 217 152 01 bolt for use with the 996 332 083 9B (40/65% GKN) diff. The bolts are M12 x 1.5 x 22,5

Hope that helps.

Thanks Bruce, that helps surely, but I looked into the catalogue also and the 999 217 152 number seems to be the partnumber of the regular open diff (although a pic of a lsd was used, the general title of that section is 'Differential') as opposed to the 'Limited Slip Differential' section, where the 996 332 276 00 number seems to come from...
You wrote 999 332 276 00 but I am sure you meant 996 as first 3 digits for this one.

I could open de 996GT3 as well as the 996GT2 and both list the same pic and part numbers for that 9B diff..

I do indeed have that GKN diff however, so I am a little confused now which one I need... Could you check if your assesment is still correct, pls?
