Hi all,
I'm actually trying to mount an old aftermarket A/C setup to my '55 Studebaker, but i thought I'd ask here if anyone could shine some light on a problem that I have. I need to block off a hose fitting for a heater hose on my water manifold, but I can't use a regular pipe plug because the A/C bracket is actually maybe 1/8" off the surface of the water manifold in the area of the boss for the heater hose fitting. Apparently one was supposed to use one with a hex recess, like a transmission drain plug. Are these commonly used for any other applications (e.g. could I find them at any particular kind of store - the Orange Box doesn't seem to sell anything but the regular square head type) or should I suck it up and order from McMaster-Carr?
Also, McM-C lists them in Type 304 and also Type 316 stainless. Which would be better? I would prefer brass if at all possible to prevent seizing but that doesn't appear to be an option. I think the ones that Studebaker used on cars without a heater were either iron or steel, but I don't have a stash of old water manifolds to steal those from.
