I have a 98 24 valve five speed with a screwed engine and plan on switching it to a 12valve. I have a 97 total loss that will be the donor. Im not sure about some of the wiring but I have the complete 97 truck for parts. Now i dont think it will be that hard to do but has anyone done this, any help will be appreciated. This is my first posting, Thanks

 

since u have the donor right there it shouldn't be mechanically hard at all, just alot of manual labor. Very doable swap, and if u run into any specific problems someone here will have the answer.
