I expect you mean the shutoff valve and "excess-flow[-preventing]"
POL spud that the regulator fastens to.  Any RV or LP place should
have the valve.  The male POL fitting with the internal over-flow
shutoff is an RV item but you should be able to use the old one if necessary.

They built the tank.

Try the above.  Anywhere, not just Manchester.

RV and gas people may refuse to work on it on that account.  But if
you take them the valve itself I'm sure they'd have no trouble
matching it.  Remember, if you use PTFE pipe tape for assembly is has
to be the yellow "gas-approved" kind.  Otherwise you must use pipe
dope, PTFE or otherwise.
