Need To Know Ford Y-Block Freeze Plug Size

I need to know what size freeze plugs are used on the sides of the 1959 Ford 292 Y-block engine. I think there are 4 plugs. Your help is appreciated. Thanks very much. JIM

 

PM mctim64 he will know

 

Dorman #557-012 for the steel plug kit.

 

The plugs in the side of the block are 1 3/4" diameter and right around 3/8" (.375) deep.

 

Right on! beat me to it.

 

Also available in brass which I highly recommend as they will last forever
