This is a truck BBS, so you probably won't get much on a car transmission here. Have you tried the Mustang BBSs?

It's a truck and a car transmission.

Didn't find any info on the tag. A 72 manual (truck) shows three different gear ratios:

170 1v 3.41 1.86 3.87(rev)

240, 300, 302, 360
2.99 1.75 3.17(rev)

390 2.42 1.61 2.57(rev)

It is known as the Ford 3.03. I don't know how it compares to the 4 speed toploader for strenght. I think the 4 speed may be stronger.

Strength is = to the 4-speed. As long as the teeth are in good shape the only other thing is listen to the countershaft bearings when in 1st or 2nd gear. If quiet, then it is in good shape. the counter shaft bearings do go out over time ( 200,000+ miles). This tranny is fine for what you want to do.

I don't know about the numbers. The 4 speeds had different tail housings for shifter mounting in different cars. I am not aware of the 3 speed having this characteristic.

Don't worry about the different numbers. These trannys were assembled from the parts that were current at the time. A part designed...lets say in 1968 (C8xx) would stay in use with that number until a design change was created, sometimes for years.
Your numbers indicate parts from '65 and '68, and some of these three speed parts were used well into the '70's.

Could it have been rebuilt? Sure, but it's highly likely that only internal parts were changed, unless case parts sustained some kind of damage, and even then they were probably replaced with similar casting numbers. I wouldn't put one of these into a resto show car, as I doubt the 460 ever came with a 3.03 (or a 460 in a '93 Mustang for that matter) but it is one tough tranny.

Check out the syncros as well.
