Here is some info. I started with a 80 3/4 4x4 burb , rusted out, I got a 89 2wd burb that had no motor,Here are pics of progress. The body will simply bolt on,( I used a lift to change mine) But no cutting/welding unless you are using a 2wd frame converting to 4x4,Its easier to find a rusted 4x4 frame..: Word of advise,Get you a 3/4 4x4 frame.If you plan on runnig bigger tires and a lift,make sure you put the reinforcing plate behind the steering box,So the frame won't crack,The 3.4 frame is alot thicker..that a 1/2 ton.. You don't want to do a job like this twice
If you have any questions at all,I will be glad to help, as i just did this same thing..Thanks,Erick
