parts hunting

[dirigoboy]

Last Spring while bush hogging my field, the pin on my hitch popped out of my draw bar and once the pieces stopped flying, I found I had a search to begin.
Now, I know this is a crawler site, but both of my tractors are 1956 John Deere 2-cylinders. One is a 420U and the other a 420C.
The parts I am looking for are for the 420U, but they look to be the same as on my crawler----at least, regarding the rear cover. One is the PTO Housing, which I snapped the ears off of. I can see where the previous owner tried to weld them on at some point. The number shown is -Part No M2744T.

The second part is the rear (differential?) cover. I need one of those also. The Part No is -Part No M2856T.

I can send the photos for clarity if someone thinks they have the parts.
Thanks

I should have rear cover on hand used, no PTO housing, but still checking if I can get new ones.
