Just for the practice and the chance it will provide a clue have you looked for a date stamp on the inner liner panel.
Will look through my pictures and see what I've got to add to the search
Warning though I haven't focuses allot of general interior pictures during trips. Always a choice - spend more time in the engine compartment, under the car, on body details .......? With liners normally in place and glove boxes normally close - not going to be easy collecting data. Hopefully a few members will find time this week to take a peek at theirs
