Servicing a PMI-1 SC, 2- ?'s

[Rolling Thunder 67]

Opening up a PMI - 1 SC for service and would like to know the o-ring size for the bolt and can you drift the valve assembly out the back with the lead seal still in place? only the second time i've opened one of these up and the brain is a little foggy. any assistance would be appreciated.
Thanks.

Valve is 012 and 014 if I remember correctly.... 🤔

Edit.... Bolts are 015....??? You can just shove that lead seal out the back and into the trash. 👍

Most of what you need to know is on there:

Thank you for input, found you can remove lead washer while removing the valve assembly. found a couple other issues which are resolved, back together and running.
