Well if you choose to do a cab swap, terrys87 has done a few on yotas and is extremely helpful. I have also done one, its not that bad(only 17) just take your time and mark stuff. Also double and triple check you took off all wires. Terry has a list of the majority of the things you need to do in one of his build ups somewhere. Few threads bout cab swaps on here. Just search
In my opinion though....rust is a battle you can't win..You fix one spot and it just moves to another.
