Crosman 1377 piston thread

Does anyone know what threading the piston on the 1377 uses?
Thanks.

@ Qyuubi786
 

if your taking about the

after market pistons, there all different. each maker designed there piston
with there own threads unless they copied someone else.

The thread is not as important as the other aspects on the piston.

We have a guy in the shop that builds pistons with no threads, he uses splines and twist locks, I asked why, still I've got no answer but they work and real nice.

I'm working on a hpa project.

I upgraded my 1377's stock piston to a flat top piston. I still have my stock piston. I just need to know what type of threading it has so I can use a 1/8 npt reducer
