My dad has a 1979 Chevrolet K-10 shortbed. He has a 12 bolt rear and a 10 bolt fron under it now. He just bought a 10 bolt rear and a 10 bolt front from a 1989 Suburban. I get to do the swapping, what can I expect in terms of differences and modifications of any kind... other than the truck falling on me(had it happen once, wasn't happy at all
)
