I've recently acquired a rebuilt starter that is supposed to be off of a '54 Kaiser. Problem is, I don't know if it came off of a Hydramatic engine or a manual trans. engine. I've heard that there is a difference. How can I tell what I have here? It is a Delco unit. Model #1107125 Serial#2J23. I know how to decode the build date from the serial number which tells me this starter was built in 1952. Doesn't seem likely that it's really from a '54 in that case, but anyway, where can I find a correlation between the Kaiser part numbers and the Delco model number?
