I popped a freeze plug on the drivers side of the cylinder head. Anyone know the correct size of that plug? I got a 35mm, but it's much too large.
Factory part number is 444668. Cross reference that against Dorman's site - it should give you a size.EDIT:https://www.dormanproducts.com/cgi-bin/vm91corp30r/classdtl.p?clt=hwrap1&sid=xeDEiVdinoilSXpE013150567702441914&tid=48749&rid=0x00368494Looks like a 1.25" size or 31.91mm.

If it is a Block freeze plug I was told it was a 35mm
