Little help please....orphaned Autolite regulators left on my doorstep in the middle of the night...I suspect by a Packard guy, but might have been a practical joke by the local Buick Club?
VRP-4002-A -- 35amp.
VRD-4001-B -- 30amp.
VRR-4004-A -- 20amp(on buss bar)

Thanks guys...should be easy for someone with a comprehensive autolite book.
