I have a parts manual for my 77 Plymouth Gran Fury wagon BUT the trim code on my plate is Q3TT and the book says it does not esist. Yes it is the Ultra Rare cloth seats but surely it should still be in the book? My problem is that the very rear Pass side piece of plastic trim on the roof pilla r is broken and I am trying to get the correct part number to hunt down a new piece. It is the Dark Tan, almost brown really that was used when you ordered the Cloth seats. Can anyone smarter than me figure out the correct part number for me please.
