Cragar Rims on 68 Camaro

[tater223]

Just finished the rebuild on my 427 and looking to swap out these 90's Weld wheels for some Cragars. I have looked long enough for round spokes with no success so I am just going to order some flat spokes for the front. Torn between 15x4.5 or the 15x6 for the front. Issue is...I have 4 piston calipers and backspacing is an issue. If you are running Cragars on less than a 7" rim, what is your combo of backspace and spacer? Really dont want to swap to single piston.
