You say the pattern is 5 3/4". I think you meant 5 x 4-3/4 which is the common Chevy car pattern from the 50's up until front drive.
There is a second GM pattern used on some larger Chevy cars which is 5 x 5 like a '72 to '87 1/2-ton pickup.
You can probably use almost any 5 x 4-3/4 wheel. Which one is best depends on what you want to achive.

It's true. I really don't do anything but browse the Internet looking for trouble... | | | | | Joined: Mar 2005 Posts: 311 Shop Shark | | Shop Shark Joined: Mar 2005 Posts: 311 | You are correct about the 5 X 4 3/4" pattern. I was interested in the (minimum) rim size that would clear the calipers. Cpp said caliper size was for the medium size GM (77 camaro). Rotor size was 71-79 camaro. Thanks in advance.

A stock 14" 74 nova rim with front drum brakes will not fit. Got these rims from a buddy for reference.
Thanks OldSub.
