Anyone have engineering diagram or measurements - 72 leaf spring rear?

While not really what you are looking for, thought I'd share:

• '67-'72 leaf spring truck 12-bolts (4x4 and 4x2) have non-staggered shocks.
• '67-'72 4x4 trucks have 2" wide spring perches 41" centerline to centerline and bump stop provisions on frame.
• '67-'72 4x2 trucks have 2" wide spring perches 43" centerline to centerline and bump stop provisions on rearend.
• According to the Hollander interchange the '70-'72 axles on GM 12-bolts are 31-11/32" long and the '67-'70 are 30-1/4" ('70 is a split year).
• '73-up 12-bolts (4x4 and 4x2) have spring perches 43" centerline to centerline, bump stops on frame, staggered shocks, and 2.5" wide spring perches.

Actually that's a good start. Thank you for sharing.

Basically I'd like to confirm measurements for my leaf spring housing/axle/rear if possible rather than "make them up" with a measuring tape. Due to the odd shape it's not easy to measure, especially with it in the truck.

Do you have measurements on the shock mounts by any chance? or overall width?

Thanks again.
