Rick,
I purchased a 1970 Maverick last year from an older gentleman who was the nephew of the original owner. The car had 37,000 original miles on it but was heavily damaged on the driver's side (door/Quarter). The car is gone now, but I have a picture of the buck tag which was located on the front Driver's side of the rad support. Looking at mine and yours, I notice some similarities.

THE TAG READS:

0645 B2 26E
T382534 62A 45

UP INTER
LO S GOLD Y INTER

The car was a 200 cid, C-4, Original Paint colour was "Beige/Gold" with same-coloured interior with bench seats.

My 1977 4-Door has the following:

0514 MV54A B3 16
L173401
SPM BAG
RAT

TT VTW 2R9D RED

This car has the two-tone (TT) Red (2R) and White (9D) paint with a white vinyl top (VTW). The Interior is RED Vinyl Bench Seats. It is also a 4-Door (54A). As for the rest, I don't Know.

A parts car that I had puchased many years ago had the following buck-tag:

0269 MV62A B3 14

T148331

RAT

4V GRN

This car was a 1977 2-Door (62A) with 200 cid, Ivy Green (4V).

You might want to contact Dave Boyer, he apparently has been spear-heading the whole buck-tag thing. Just as a note, the later cars (1977's of mine) had another tag underneathe these tags, but were real thin and stamped with random numbers and letters both inside out,and upside down. I hope this sheds some light on your problem.

Good luck,
