Mechanical stuff will likely be found over there. I assume you have an A with a flathead. Spoke to a guy this a.m. that's building a '28 roadster with a '39 flatty, '40 juice brakes, etc.
I hang out here, on the early V8 barn, and on the Hamb. That way all the bases are covered. There's also an AV8 social group.... click on community > social groups, scroll down to AV8 group.
