8" Rear end question?
I have a 8" rearend from a Mustang that I am putting into a 1950 F-1 with a 302/C4 combo. I want to change the gear ratio from the 2.79 in the current third member. I am doing a salvage yard search and need to know what years the 8" was used and in what vehicles. Any help is appreaciated

Check out these boys:
http://www.currieenterprises.com/
Check their "Alumin8" item. Lightweight, high strength 8" diff. $390 or so.
That's as far as I went looking, not sure about details.
As for factory 8": These were in small block V8 small and intermediates like Falcon, Mustang, Fairlane, Comet etc.
These diffs ran from the early '60s to probably the mid '70s.
This is another guy selling 8" diffs. Looks like he sells Currie stuff. See the site and get the info:

You may luck out and get one from the scrappy, but these were kind of a weak diff and if they've been out in the elements for years, you could have real howler with used one. (like the one I got for $50 in 1971.)

Mustang II's are your best for finding a set of gears. Buying used 8 inch gears can be exspensive and hard to find. If your looking for a trac loc then be ready to pay for one. About twice the cost of a 9 unit.
