Engine/Transmission (1994 - 1998) Engine block frost plugs

[RPalermo]

Hi all,

I'm doing some cooling system work on my 95 Dodge 12V. Does anyone know the correct size of the frost plugs? Are they Metric? I measured the block heater at somewhat over 2 1/4". My local parts store doesn't show a listing.

Thanks

Rick.

You have to get them from Cummins
