1962 trim code deciphering

I've already sent in for PHS documentation, but I'm impatient. Here's what my Tag looks like:

Pontiac Division General Motors

Here's what I know, from checking various sources on the Internet:

- "62-2167" means it is a 1962 Pontiac Tempest

- "T" means "Caravan Gold Poly", though the car is now "Cameo Ivory"

So what I'd like to know is that the "BC 407" and "214-TOP1" mean. Any suggestions, besides patience?
