1964 c10 help

[DBear]

Hey guys. ...not real familiar with the 60-66 chevy stuff. I am looking at a 1964 c10 swb that is blue in color with a small white section on the bed. The motor is a 6 cylinder with a standard trans. Would like to get some advice on this truck. Not sure if it is the original color but the paint looks pretty darn good and straight. No rust at all that I can see. I will try to post pics as well.

Vin# 4C144 H 150727
Paint code# 503AA
Trim code# 762AA

I looked the vin up but couldn't find the H in the decoder.

Thanks for any help you can provide!
