Stortening or stetching is no biggie... one big advantage of using a S-10 chassis is the unbelievable amount of add on's out there.. if you want a ride with air ride.. suicide doors have you covered, with basically simple kits.. but i'd want to put it on a vehicle where everything looks right... the wheel base is easy to change just have to cut a little.. not a real intense job... if you have to narrow it.. I don't think i'd want to use this setup.. now If i were building a rod from scratch.. I wouldn't go this way if i was looking for a premium set-up.. cause if that' the case i'd build a frame from scratch.. but the s-10 setup is a setup that could be used on many body's with good results
