Just a heads up. If you use a donut tire on a posi unit it will cause damage.

Re: Looking for spare tire and rim {wtb}
I'm in FL right now, but will be back up in Troy, NY the end of May. I have, I believe, two donut spares in Troy. My '86 IROC-Z28 is for sale down here in FL, so I won't be needing 3rd gen parts I still have in NY. Let me know if you're interested.

Re: Looking for spare tire and rim {wtb}
If you get a flat in the rear, you have to move the front tire to the rear, and put the donut on the front. Otherwise if the two rear tires are slightly different sizes with the donut on, the LSD will slip all the time during straight driving and wear a lot faster, possibly overheating too.

If you have the stock IROC wheels you can't put the fronts on the rear.
