Thanks - I'll look for the other number by the starter.

Tha stamped number by the distributor is interesting. I thought they stopped 1st series production in March of 1955 but the motor stamp is dated June. Anyone have any ideas?

I'll post the block number tomorrow when I find it.

In case you can't tell this is my first attempt at refurbishing an old truck. I'm starting at zero and have a lot to learn.
Thanks, Steve
