"M" Caliper Finish

[rw7810]

Does anyone know what the OEM finish was on the 70-71 M calipers?? They are cast iron and tend to rust. I was going to powder coat them in a cast aluminum for appearance, but saw a picture recently of late 60 calipers that are yelow zice finished. That looks quite good also. any opinions???

Bob,

Cadmium plating was the original finish, so yellow zinc is a good choice these days.
