The "caddy kit" uses OEM Cad parts I think. I don't know of any aftermarket "caddy kits" (which doesn't say a whole lot being I don't know much about "Kits" for these trucks to begin with). That would count out your S-10 being there is no Cad with parts that innerchange.
I did see a pretty neat kit for your truck lately, I don't know what it was called but it made a pretty neat "ElCamino" looking rig.
i think it was in the sport truck magazine that someone had a blower on a v6 and it was stuffed into an older s10 with an escalade clip on. i just want to know where i can find something like that because that truck looks amazing.
