TR2/3/3A TR3 oil gallery plugs

[TomMull]

I need a couple of oil gallery plugs for my TR3 block. These are the ones behind the flywheel and the front cover. My Moss catalog shows them as 328-255 NLA. They appear to be aluminum, tapered threads and appear as though they have been screwed in and cut off flush so they look like core plugs. The thread size does not match anything I can find. Any help would be appreciated. Tom

TRF shows them in stock, P/N PU1404/3 (which is a stick of 3 of them that has to be cut apart).

Or what some people do is re-tap the hole to standard pipe threads and screw in a socket pipe plug.

Thanks Randall. I can't find things on their catalog so don't generally look. Stick of three? HMM. Sounds like you screw them in and cut off the excess. Wonder if that means they are not tapered? I'll look and see if there is a seat in there. Tom
