Colorado Swap?

[mr48chev]

With almost all frame swaps, subframe swaps and other chassis mods you are going too do some or a lot of cutting and mods. That may be raising the bed floor a few inches, trimming out front end inner sheet metal or other mods.
I've never knowiingly seen an S-10 swap using the Code 504 it that allegedly sets the body high enough that you don't trim any metal. That would be the case with swapping the 59 body onto a Coloado frame, you aren't usually going to set the 59 right down on the frame rails unless you plan to have it seriously low, you are going to space it up off the chassis a tad for clearance.
