I don't want to re-invent the wheel

I just bought 15 x 6 sbp cragars for the front with 195 60R15 tires. I think the wheels have have 3 3/8 back space. Mine has front disc conversion, so I was a little worried about fender clearance on top. Fit good, except I wish i had gone to 70 series instead as the 60s in that width are pretty short and I could have used a little more ground clearance.
