69-72 73-76 lift kits...

[RANDY COX]

Ok my question is what's the difference in these lifts, on the 69-72 I know they used the square type u-bolts in the back, are there differences in the front springs....my truck is a 72 frame but it has the newer u-bolts that bolt from the top like the later yrs not the square type...but if the front springs are the same then I can order the 73-76 lift...But I'm thinking the front springs are different maybe wider not sure anybody want to chime in and enlighten me...Thanks....
