As far as I'm aware, anything half or three quarter ton is 42.5" spring perch width after 1973.

If I may so as ask, what are you planning on doing with the suburban? A 10 or 12 bolt is strong enough for a regular driver.

The original idea for the rebuild was as a tow rig for 20' Argosy [by Airstream] trailer. Sold the trailer. It has a 454/TH350/NP205/[-12-Bolt 3.73 Auburn Posi]. BBC had an engine fire. Needed rebuild. (Carb burn really.)
It was totalled by Farmers Insurance. Now I have the salvage title.
Looking at a new engine [diesel, 383, or turbo 292 ?], new tranny [700R4?] rebuild xfer case. Needs new rear axle since I stole the only good part that was on it for my GMC -- which I use for work.
A machinist I use, has a 7.4LS/ 4L8E for about $2700, but I'm afraid of the new school computerized stuff.
Maybe I'll get it running with a 292, as a light bomber. Hate to see it deteriorate.
Can Moser custom cut 6 lug axles for a 14 bolt free floater?
