I'm 21 just starting out my mechanic career, and I have a 2000 Chevrolet Silverado z71 4x4 with the 5.3l that either needs a new frame or to repair the old frame. Now with that said i am looking at at a 2000 Silverado that's only a 2wd but other than that its the same dimensions engine and everything as my original truck would it be possible to convert the 2wd frame into a 4wd and do the frame swap like that. I would just buy the right frame at a junkyard but as far as i know California has some stupid laws prohibiting it. Does anyone have any suggestions as to what i should do, get this 2wd frame and start the conversion or just wait for a 4wd to be parted out near me or just pay to have this frame pulled but a few shops I've talked to say the damage is a little to extensive? Thank you for your help.
