Freeze Plugs

[Dave_1972]

Quick question - anyone know what size the freeze plugs are on these 318's?

I assume they are all the same size - but in particular I need to replace the one by the starter motor.

The bigger ones should be 1 5/8". The smaller ones should be 1 1/4".

I never measured them, I just get the kit from Mancini Racing and put em into the holes they fit in.

Thanks!
