[Piper]

hi

We're at the point of starting our Mk2 but don't have a rad cap. I know we can run for a bit without 1 but need it for longer trials. The cap was long ago stolen during vandalism. It looks like a 2" threaded cap is required. Does anyone have any leads on what to do, can use as substitute, ... Is there an aftermarket part available??

Please help!
