Not all 2wd's are silverado's, its different trim packages radio, heat, ac, etc. What exactly are you looking to swap over? The spindles will slide into your stock ball joints if yer runnin a 63+, that will give you disc brakes etc.

When I worked for Checker, I checked about the 1.00" and 1.25" rotors and it was the same part number, I wouldn't worry too much there, I've swapped back and forth in the past without any issue.
