8 3/4 rear, small bolt pattern for 1968 Barracuda?

find 10" drums with what seems to be 2 1/4 - 2 3/4 breaking surface
Typically the machined face on the drum is wider than the shoe. So a 2.25 width might be spot on for 1.75 wide shoe.

2.75 might be for 2.5 width shoe

. 10 x 2.5 is later than 1968

I think it was in the 70s when that happened, might even be on 8.25 axle
