Re: 89 crew cab k20 4wd twin turbo cummins swap
I like the mirrors. I was going to do the same thing. If you end up blowing up the 14 bolt you could step up to a dana 80, or get an AAM 1150. The AAM is the "new" version of the 14 bolt and is just as strong as the dana 80. Its what is being used in all the new chevy and dodge trucks.
