Do you think an 8.8 inch rear end from a 1994 Ford Ranger would work for the Cat? any adjustments or welding?

my rear end is an 8 inch and had had enough, one of the seals gave way and its now leaking gear oil out the passenger side into the drum...

Replacing the rear axle seal on an 8" is a piece of cake. remove wheel. remove drum. remove 4 9/16-head 3/8 fine thread nuts holding axle retaining flange. pull axle, replace seal. re-assemble. $5 part. 30-minute job, tops. You'd spend twice as much time and thre times the $$$ to put an 8.8" in its place.

Yeah, you're talking about an easily serviceable part there.
Much easier than making an 8.8 fit.

Aren't they the same? meaning, an 8" from a cougar is really 8.8"?
I'm learning today I guess.

No, 8" and 8.8" are NOT anything alike! The 8" is like the 9"s baby brother. Both have center sections that load into the rear end housing from the front. The 8.8" is more like a Chivvy 10-bolt. Loads from the rear.

If the vent on the rear axle housing is plugged, Differential gear oil will be pushed out at the weakest point. Check the vent while you are down there.
