Re: Big Bird - 1972 Longhorn K30
For the bolts that go into the Dana 60 housing I was going to get bolts that are 3/4” longer. With top plate snug that is the gap measurement with a caliper. A little more info I discovered in my research is a standard K20 came with two leafs in front. If your SPID says heavy duty front spring there should be three leaves. Some may already know that but something new I discovered looking between a few different K20’s I have. Also picked up the right ubolts for the rear and new bottom plates.
