I am pretty sure the plastic filter was used on the assembly line. A lot of info showing that, IMO. And the replacement was metal. My Satellite only has 35K on it, so might have the original filter, BUT I am a little doubtful on the location of it.. another Mopar conundrum,,
Here are 2 different 1966 Satellite 383 4 spd cars. The first one is an original owner 28k miles garage kept survivor. The second is a restored survivor.
