Any Chance that Sheridan and Cocker Valve Body and Exhaust Valve are the same?

[Rolling Thunder 67]

In the middle of getting a Sheridan SB back up and running and just rebuilt the cup seal, not an impossible task but was a little fiddly. I was curious if the valve body and cup seal(exhaust valve) from a Cocker would be a cross over solution. In my perspective the early Cocker valve body and cup seal(exhaust valve) looks identical. I can take measurements for the Sheridan, however i don' t possess a Cocker for measurements. Also would like to know if the overall length of Cocker Exhaust valves has stayed the same? I was wondering if any of Sheridan Guru's would know if this is a feasible alternative or have used a Cocker valve body and cup seal(exhaust valve) for a Sheridan, as this would make sourcing a cup seal for sheridan's a little easier. Thanks for your interest.

The cupseals are cross compatible. I've never tried swapping valve bodies around, I'm not 100% that they will. I think I read somewhere that Bud changed those dimensions slightly, but... the Sniper was essentially a PGP body kit, so it's very possible that it will work.

Hi Jordan, thanks for your input. was thinking along same lines. will probably find out that they are slightly different.

I do have a Cocker valve I can try to pull measurements from, if you want. Just let me know what you need measured.

EDIT - turns out I still have a CAD drawing saved with measurements.

Thanks Jordan, know i can cross compare and see if my idea is feasible. time for the calipers and the Sheridan internals.
