Fender tag

[1973dusterkid]

I am going to look at a 73 or 74 duster and I was wondering if there is a sheet of VIN tags that I can take so I can check the fender tag on the car and see what it came with.
Also how would I tell it the motor in it is original and were is the numbers on a smallblock mopar or a bigblock mopar?

take a pic or write down the tag info and post it . the best i can do is:
C=/6
G=318
H=340
L=360

maybe someone else can be more help

Were could the letter be on the fender tag

this will be the 5th digit on the VIN tag

the VIN # also appears on the fender tag in the bottom right corner
