To the best of my knowledge the front is a direct bolt in and also the the rear, but only if it's from a 1 ton truck. 14 bolts were also used under 3/4 ton trucks and 1 ton vans, both of which are spaced too far apart for spring perches to be direct fit under your truck.

I'am doing the same install in my 71 K20.
