hey trader. I think the way to go is with a mustang 2 or plymouth volaire front end. the plymouth is quite easy to install. you need simply notch the frame rails (rather than cut them off!!) and box in the rest of the frame (to the back of the cab is as far as i have ever gone). then you can still bolt on your stock bumper and the core support bolts back in the stock location with no fabbing. the plymouth is a torsion bar front end, so doing air ride or just simply lowering is a breeze. as far as an s-dime frame................it can work, and will actually be pretty good as long as you pay attention and dont rush the fabrication involved.
no one wants an unsafe vehicle on the road!!
if you decide on the s-dime frame, chassis tech's dropped spindles for that application have a slightly wider stance than stock. my front end was widened by approx. 3 inches. so the correct tire size and wheel offset can look and function really good for your application.
also ............you may want to check into the s-dime blazer four door chassis. (pre 94 or 95)
they are completely boxed from front to rear, the only downfall is that they have a step up in the rear around the gas tank, so you would have to cut the frame to level it or step the floor of your bed to accomidate (not recommended). <img src="graemlins/pimp.gif" border="0" alt="[pimp]" />
