Today? 65 Barracuda ENGINE # knowledge needed!

This was an afterthought - we are going Friday A.M., though so if anyone sees this...?

...trying to help a friend who is going to look at a 1965 Barracuda.
I finally made a deal on the one I ostarted a thread about, just have to finish the details$.

~Q=Anyway,...1965 V8 car...I think the VIN is in the Driver's door jamb?

~Q=Trim tag is on the driver's inner fender, right?

~Q=On the V8, where is the # that would decode it?

On Chevy stuff, there used to be a casting #, telling what the engine was in raised letters...thena stampled in, that was more of a sequence # only. Did these Mopars do something similar?

Once we get it, where to decode it? I found a VIN decoder, but?

THANKS!
