help with fender tag

Not exactly, but it should contain some info from the fender tag, (or vise versa, however you want to look at it).
This is based on my knowledge of my 67 Barracuda.
Judging by your fender tag, your VIN should be:
LP23 (letter code for the engine) (number code for the year, yours s/b an eight) (number code for the assembly plant, 2 is for Hamtramck) (6 digit sequence number)

So, from that and using B for the 225 engine: LP23B82123456

Your trunk stamp, and I think the rad support as well, s/b:
Year, plant, month, day, and the last 5 digits on the fender tag bottom row- but I think Darts have 6 digits there.

So, from your pic I only see 14: 82828140000
