I'm not using the same computer anymore....I doubt I would be able to find them.
The 86.5, 87, 88, and 89(non airbag) splines will match up. The Cruise control functions on the wheel won't without more mods(I didn't do these)
The horn ring off the MKII wheel needs to be atatched to the rear (use the big hole for the horn tab into the wheel - you'll know it when you see it) of the MKIII wheel. Use REALLY short screws or they will touch the metal part of the wheels and will scare the b-jesus out of you when you try to mount the wheel... ask me how I know. lol
You may need to widen the hole in the cover on the column, I had to take off ~1/16th of an inch so the wheel would fit without rubbing.
