Cub 1641 Differential
 

I have a recently acquired 1641. In cleaning things up I see that there are 2 threaded holes on the top at the back of the differential just in front of where the back plate bolts on. Are these just 2 bolts that are, for some reason gone, or does something else thread in these holes?

I'll attach a couple of pics, the first is of the back end for reference and the second is a closer pit of the top of the differential and the 2 threaded holes.

Thanks in advance for any help.

The rear PTO bearing was bolted to those holes on the Supers, theya used the same case.

Got it Sam.

Thanks
