that's a nice-looking wheel. I have a smaller Grant GT with leather wrap sitting in my garage from when I had my first 67. That wheel is a POS (not the greatest, quality-wise) and never fit quite right. I don't know if I got the wrong adapter, but I bought the one that said "fits 1967 Mustang" on the box. I installed the wheel on the 67 I have now, and it doesn't fit this car either.
I'm probably going to get a LeCarra next.
