Your budget is the only real limiting factor whith these taco toys. If you want a sas then go with a link suspension and rebuild the frame to accomadate the narrower axle. Spacers or the ifs hub conversion will be a must. If it is a regular cab then don't waste your time with that thing, pick up an earlier body and drop in the 2.7 for more power, and a lighter package. The reg cab taco dosn't have any more room than the 3rd gen and is alot less mod friendly. I bet you could pick up a 3rd gen with a blown motor for what you could mack selling that cab.
There is lots of info on
