I have a question about the axels that are under my 72 international truck.
the engine is a 304/ t18 and an unknown t case. te rear looks like a large 44
the front cover looks like a 44 but the spring mounts look like dana 60 stuff.

and help is greatly appreciated.

The front is a 44, the rear is a 44 or a slim possibillity of a 60.
