I bought a Grant GT Challenger wheel for my '82 Mustang, and I loved it. I also picked up one of those sew-on leather covers from the same parts store I'd purchased the wheel from. I was fortunate that it had the full wrap (around the thick hard foam rim, no less), but the diameter was too large. I wound up cutting the cover, trimming to the right length, sewing the ends back together, then installing it with the seam at the bottom. Looked almost like a professional job - would've looked every better had I been smart and pulled the wheel off the car to sew it on. rofl
As far as which one to purchase, that's a tough call. Your best bet would be to take a clothes tape and measure the thickness (circumference) of the wheel rim itself, then measure the wheel's diameter. Check with the local parts store - if they have some sew-on covers, you can maybe see if something they have would fit, but make sure the perspective covers have enough 'wrap' as well as the right diameter, otherwise, it's just a waste of money.
I currently have one of those old-school covers that you wrap and secure with the plastic lace - I love it... but it doesn't have enough 'wrap' to completely cover the wheel (there's a gap on the inside of the rim all the way around. I'll be looking for another that will actually fit better, or go with a leather sew-on cover if I have to. (I just grabbed it from the local parts store, not paying attention as to whether it would fit or not). It does the job well enough, but I think I can do better.
