expansion freeze plugs

Another freeze plug question - Does anyone know a stockist for the expansion type of brass freeze plugs (they have a nut on them, that as you turn it squeezes the core plug flater and hence it becomes tighter in the hole - easy to fit in confined spaces, no need to swing hammers or make dogleg tools that put the plugs in crooked). I know Hemi hot heads site does them, but looking at my brothers Desotos ones, they are not the same size as my Y-Block.I imagine someone must sell them in various sizes.

 

Lots of that stuff is produced by Dorman. I will try a search.

Click on the Dorman link. That site got weird on me. Search for expansion plugs, copper type.
