I love the idea of using a S10 4x4 but the kicker is I found 3 different companies selling conversion kits and non of them will work with 4x4's. I may give thme a call and see if they would modify me a kit if i give them a specific year of S10 4x4. If there are only a couple of pieces that would need modified i'd be ok with that but i'd like for most of the kit to work or it's not a time saver to buy a kit, and a waste of money. I'll keep digging online and see if i can find out if someone has used a 4x4 frame and what all was involved. Thanks again!
