Hey guys. Can't find this info and didn't tag it at the time. Awhile back there was a thread regarding a 14 bolt setup that would be a very close bolt in for 67-72 trucks. It was said to from a cab over truck that had spring perches already placed correctly. Anybody know for sure, what years, info, etc. Thanks

73-86 one ton trucks have 40.5" spring centers, same as a 4x4 67-72. Shock mounts have to be re-done. 3/4 ton trucks have 42.5" spring centers so shock mounts and spring pads need to be moved.

Mike C-
One more question, if i could. This would be for a K20, do I need to look for 4x4 axle or 2 wheel drive or does it matter. Just trying to narrow down the search. Thanks

I think they are all 42.5 in the '73-'87, but don't remember for sure. The 67-72 all of the 4x4 are 40.5 and the 4x2 are 42.5.
