Does anyone know if the 1972 Cadillac Eldorado steering box will work for my saginaw power steering conversion?:confused:

Any Saginaw box will work with your conversion. What are you looking for?

FYI......72 Caddy Eldo box has a casting number of 5687962, a 13/16" input shaft, and the turns ratio varies from 2.75-3.5 turns. Some say this may be too quick for a short wheel base vehicle. I have only driven 4.25 turn boxes on Cruisers.

Eric, I have a 4 bolt 13/16" box casting# 5691676. Is this the 4.25 turn box? I'm hoping so. Don't know what it's from.

They used that casting number (5691676) for 3.75-4.25 turn boxes. Check the bottom of the box for a "6" or a "76", then count the turns. Let us know what you find out.

stretch your wheel base to 104 and get any box you want, i have the 4.25 turn i think anyways! jimMy

It's got a "66" on it. Counted the turns and it's just under 3.25.
I'm 100" wheelbase. Hope it's not too fast but it was free so I'll give it a try. Do the 4.25 boxes also have 13/16" input? Cause I allready ordered the Borgenson for this box.:eek:

Of the 4 turn boxes I have seen, they all have 13/16" 36 spline shafts. I am sure there is always an exception. Search for late 60s, early 70s GM cars. They will have 13/16" shafts.

Hey guys, I too have the caddy eldo box. It seems to be the 2.75 turn box. I am building a crawler out of my fj40. Would this be acceptable for the hydro assist?

fwiw, i have seen a bunch of 4 bolt 4.25 turn boxes in the older grand cherokees and grand wagoneers as well.

personally, i would'nt run anything other than the 4.25 turn box on a cruiser. pretty scary on the freeway, unless you're into "instant lane changes".:laughing:

My cruiser is offroad only.
