I have the engine and transmission out of the '74 for cleanup. The transmission output flange still has the original style 4-notch nut on it and I cannot find one of the special sockets to buy anywhere or borrow locally. I thought I had it worked out locally but it is not to be. Nobody I know has one of these sockets. The new nuts do not require the special tool.

Do any of you have this tool, and can I use it? I'd be happy to pay for shipping and a rental fee. Couldn't find it in the tool rental section.
