Cool Jim, it would be fun to chat. Taking the Z to JCCS is in the plans, I'll just have to talk it over with the fiancee (will be "the wife" by JCCS time!).
I've actually been selling off my rims, I had 4 sets of 14" rims at one point! I still have 2 sets of slots, one set of 14X6 and the other 14X7. The 7-inchers don't fit within the stock fenders though. The funny thing is, is that the other set I have is almost just as you describe! Here they are mounted on my first 240Z:
Besides those, I also have a set of 14X6 turbine-style wheels. I just wish there were decent tires for 14 and 15-inch tires. The lack of tire choices have me looking at 16s. I'll probably be boring and go with another set of Panasports unless I find a wheel that works well with the green color and vintage motif of the car.
