Not to hijack, but I will also be interested in this thread. Now that mine will start and run, I want to clean up and eliminate any components That aren't necessary. Is it feasible to get down to only the vacuum advance, tranny vacuum modulator, and power brakes if equipped? Mine has a large diameter hose, like a heater hose coming from a port on the exhaust manifold. Did it used to go to a no longer present air pump? Anyway, sorry to jump on this but I have the same interest as MyProject...
