PE50 vs Gen Movment

Hello,

Am looking to a WD 1863 case mod.

I have a Gen Moonswatch

I was looking to do it with a rep/fake to start with, my concern is cutting the stem and pushrs to fit a PE50, if and when i swap to a gen movement

Will the stem/pushers still fit/work?

My question basically is the PE50/Gen movement close in size and pusher placement?

Iv tried to google but cant seeme to get much information in regards to the GEN movement.

Thank you.
