I have a 92 2wd LE extended cab, 5 speed with 103000 miles (I'm 2nd owner) California truck until 1 year ago. I bought from original owner (85 yrs old), and he gave me reciept from Gale Banks shop in San Bernadino Calif, where he had Banks turbo, Banks exhaust, Banks injector pump, and a huge Banks intercooler installed. The truck is perfect inside and out. I want to change it to 4 wheel drive truck. I'm looking at a 93 ext cab LE, 4wd to buy with 318000 miles. It has auto and some rust on rocker and cab corners, but other wise looks good, drives good, no front end wobble. Looking for input as to how hard to do and is it worth it. I gave way to much for 2wd drive, but I knew the truck and wanted it, I paid what I had to too get it. Need some direction from you guys.
