newb here 1st question

Hi guys!
I picked up a 49 chev stepside the other day. I have always wanted a classic truck. It needs tons of work and i'll be learning as I go. I have been working on classic motorcycles for the past 3 years. It's time to turn my attention to this truck. There are way to many blue hairs here in Florida for me to feel safe riding them on the street.
I really don't know anything about these old trucks. Except that I like em.
Got a question though.... I don't see a VIN number anywhere.. How do I know what options this truck came with? Origanal motor, color etc... I read somewhere on here that the 49 and 50 are the same. That's all I know.
Thanks
