Also look at this website: 67-72chevytrucks.com. They have a subsection on AD trucks 48-54. Several builds using s10 frames. The s10 utilizes 5 x 43/4" bolt pattern wheels so you get 5 bolt wheels. Personally, I'm building a '51 GMC 5 window on a '83 standard cab long wheel chassis. The website will offer detailed tips on mounts, moderate welding skills and a 4 1/2" grinder with a cut off wheel will handle 100% of your needs!
Blazer s10 front suspension, 4x4 rear diff with disc, 5.3 and 4L60E trans with A/C.
My build is under bsccp
Enjoy
