Re: Leaf spring perch variations???
I concur with the above. 40.5" on 67-72 4x4 and 42.5" on
73 and up 1/2 and 3/4 ton with the K30 at 40.5". The '69-'72 4x4 trucks also use 2 1/2" wide leaf springs and the 2x4 use 2" wide springs. Longhorn trucks are 2 wheel drive but they have 40.5" spring centers and use 2 1/2" springs just to mix things up. Not a '67-'68 guy so can't speak to what they had but I know the springs are different.

Re: Leaf spring perch variations???
I don't think so. 4 Wheel Parts shows replacement axle the same for '70-'81 8 7/8" axle.
