My son has bought 3-4 of them for various old mopars, all aftermarket, all from the same place/ all have been junk.
He is re replacing the most recent one, got real lucky at the last swap we went to, a guy had 2 NOS ones for his application.
(This one's a 72 C body wagon) I shoulda bought em both
The seller did say that he's sold a few to guys who cut the tube and modified it to fit their application, at least that way they got new electrical guts
