John, I have a 366P. Pot metal body does not appear to be cracked. BUT...the shaft is stuck, advance parts are stuck, no cap, some extra parts possibly from one that has fallen apart. Use my direct email below to contact me and I will send pictures. I have another, cast iron body, distributor (missing the tag) that looks like it would work by changing the drive gear. It uses the same points and rotor but a slightly smaller cap than the 366P. I have used REMY caps for it.
