68 is 22 x 26 x 1 1/8" (different rubber bushings but 2 or 3 leaf)

69-71 is 22 x 22 x 1 1/8" (same bushings as '68 and 2 or 3 leaf)

For '72 it's 22 x 22 x 1 1/8" (2 or 3 leaf)

The wierd part is that it shows the dimensions ecactly the same but it also says they do NOT interchange. Have no idea why. It only lists '72 jimmy, '72 chev and GMC conv. cab trucks as interchange. Oh I guess this is pretty old, sorry.


then '73 up is 23 1/2 x 23 1/2 x 1 1/8"
I have a 67 4X4 frame and the front springs on it are 44" just like the 69 to 72. I don't think the Hollander manual is right! I want to use the 73 and up 47" springs instead of the B52 swap but I dont know what width they are.
