I know they use a long wheel base regular cab s10 frame under AD chevy trucks all the time. That might work for you too. a Dodge dakota might be a good donor too. Might want to take a tape measure to a wrecking yard and see what you find. I have three of those trucks, two 1/2 tons and a 2 ton, I can tell you that clipping with an s10 frame will be a challenge, there are some differences in width.
