I have been messing with these cars since the early 1980s .... I NEVER knew there were fiberglass trays until reading this. I have only parted out one 69.5 in the course of all this and pretty sure the tray was gone. Pretty cool to learn something new after all this time.
Thanks for the photo! I actually just got one of those my self, they are pretty cool pieces. I know what you mean, my friend Richey is obsessed with these cars, he is always showing me something new! He gave it to me for a great price, wasn't gonna argue in the least. We have made it our goal to collect as many rare pieces for these cars as we can lol.
Here's the part number for the fiberglass unit. The second picture is of another number painted on with a paint marker as removed from the car. Don't know what it might mean. - Matt
Thanks to you guys.. I know way more about Mavericks than I ever thought I would end up knowing when I bought my Comet. lol
