You need a 2 wd long bed standard cab 1985- 92 s10. Closer to the 92 the better as the earlier ones have a lot of flex in the chassis. Standard cab is the key here . You will need wheel spacers on the front and swap out the rear diff with a s10 4 x 4 rear or camaro , nova etc. my truck is on an s10 and worked out great. Parts are super cheap.
