Poly freeze plugs

61kustom Posted 2022-09-13 12:40 PM (#624243) Subject: Poly freeze plugs Regular Posts: 62 Location: arizona I lost a freeze plug in my 61 this past weekend, I did some searching on here and got a few part numbers but can't seem to find anything in stock. Is there a more up to date part #? I also read that early polys don't accept cup style plugs, but will later a poly like mine accept a cup style instead of the disc? I've got a rubber plug in it now, so I'm just trying to get my ducks in a row before I make a mess again. mstrug Posted 2022-09-13 5:19 PM (#624254 - in reply to #624243) Subject: Re: Poly freeze plugs Expert 5K+ Posts: 6502 Location: Newark, Texas (Fort Worth) There are polly charts and such, but if you have the cash.... https://www.moparmall.com/1955-59-Ply-Dodge-DeSoto-Chrys-Core-Plug-S...
