H'mmm. 1648BX7 is formatted like a colour-coded trim item, but the number seems much too low for an item that didn't exist until 1963. I can't find the trunk mat in the '65 FPC, though.
Thanks for your input guys. I think 8 is August, date is 22, 1 might be the first shift but can H stand for type of mat? Like Herringbone, Gray plaid etc?
Dan! I checked out the interior section too but no trunk mat! In section 23-20-29 I found Mat, rear deck floor part#1613TA7 but I'm not sure it's the right one!
Did get some thicker paper today at an Art Shop. They even had it in black! I transferred the dimension and used a sizzor to cut them in shape. So now I can add them next time I'll do the headliner.
