I've had a couple of PTO drives, and I forget which was which....but one of them could be broken down re-assembled with the shaft extended out the front or the back. Don't remember if it was the NOS one I got for the M715, or the NP205 one I got for that swap that I loaned out to a buddy to test fit and it got "lost".

We took the NP205 apart cause it had water in it at one time, so I'm thinking it was that one.

I'm thinking they were both basically the same, with the NP200 drive being straight cut gears, and the NP205 being helical. Of course, that was over 20 years ago now... You might get lucky.
