Piston identification required

[Will Brown]

Hi all looking for a little help found some pistons for sale for my rebuild EAC 49/53.Number on box Ford C01T-6199-DR.

Parts book for Merc. pistons lists as (P/N EAC 6108)
If they are Ford pistons they would not be correct to use with Merc. crank.

As a wild guess it is a Canadian part number for the 1940 large truck, aluminum piston, with 3 1/16" bore, 4 ring, with 0.030" oversize.
