i bought my front end adapters from ECI... they have a very informative catalog and a good website:
www.ecihotrodbrakes.com their adapter will allow me to use chevy rotors and calipers with my stock straight axle...
i'm building a '35 pickup w/350 tripower & 4speed and i'm using an s10/2wd rearend... my bolt circle will be standard 4 3/4" chevy so i can use about any wheels i want too and have the front match the rear... most likely chevy rally wheels as i'm striving for an all chevy theme as much as possible... plenty of chevy stuff available too...
sounds like you'll have a great truck...
