Thread: Differential Help

Tweet

I'm looking at a mid-60's project car that has stalled and the guy is wanting to get out from under it. His post says that he put in a

9in rear axle (from 72 international scout) built with a detroit tru track diff and 3:70 gears.

Can anyone help me understand how the International Scout differential compares to a 9" Ford before I go to lay eyes on this beast?

Hey Roger,
According to Wikipedia International Harvester Scout - Wikipedia, the free encyclopedia and a couple of other sites I clicked on, the '72 International Scout came with a Dana 44 rear with optional Trak-lok. It was probably 3.73 gears.
Hope that helps a little....

Ok, Roger, the curiosity is killin' me! What is this mid-60's car and what did you decide about it???

It was a '65 Falcon 2Dr Post with a 302 and a ton of parts that had been bought to re-do the engine - kid needing money to move to Cincinnati. It was advertised as "minor rust on the lower rear quarters, but in fact had huge holes in three of four fenders, plus the floorpans - kid swore you couldn't see any rust from the top, and said the PO had put in new panels. Maybe so, but if he did they were welded over the old. Dave says that he just reversed two words - "essentially rust free" when it should have been "essentially free rust". I passed. It was a Ford 9" diffy though, and he had put a brand new Detroit TrueTrac in it, with new JEGS gears. Apparently back in the 70's IH was using a bunch of different suppliers for their powertrain, and there was not much consistency in the line.

Too bad, Roger. Sounds like it could have been a fun project.....minus the rust, of course! Thanks for the update!
