Hi John,
Welcome on the forum and congratulations on the purchase of the early Chev!
Some info on engine/chassis numbers of C8's can be found here on the forum:

More info on engine numbers can be found in the link below. A lot of the info on this site actually comes from MLU's David Hayward, who has sadly passed away a few years ago.

Judging from your description that it has a 2A1 body, I wonder if it could be a C15, in stead of a C8. Is it a wooden body?
Please post some pictures of the truck when you have picked it up.
