I have one that a previous owner painted the center section Medium Red. Most likely it was Bob Steiger... If you don't mind masking off the rim and re-spraying black over the red, you can have it for free. I gave its mate to another forum member last year so this one is an orphan. The tire most likely is 25+ years old.
If you're still having your garage sale next week I can deliver it since I was planning on coming anyway.
Do you still need the 88 GT/Formula lace style front rim? If so I have several to chose from because somehow I ended up with 5 front rims for 88's. If you still need one please contact me and I will send you HiRes pix and prices. Thanks.
