So one of the neat things about setting up this blog site is that I get to see the search strings that lead people here. One of the strings that I’ve seen for two months now is a question about what the measurements of the deck lid on a Ford Model A are. The answer to that question is something I would like to know too.
The 29 Coupe I’m working on has a rumble seat not a trunk but I’m assuming the lid is supposed to be the same size with either one. I seriously doubt each and every lid originally installed on any style (coupe, sedan, roadster, two door, four door) Model A is the the same size anyway. They certainly wouldn’t have been able to measure the jam gaps and find them all the same or roll a ball bearing along them evenly – if anyone remembers that old commercial. On the coupe I’ll bet I have over 15 hours adjusting and aligning the rumble seat lid. Of course all the braces, drip rails, and hinges were completely disconnected except when I would clamp them in place for a temporary check on the lid alignment. Rumble seat lids are notoriously difficult to align and I certainly got a lesson in how many different moveable parts there are.
During those 15 hours I measured the lid several times. I measured the front, back, sides, and diagonally. Not only was there really nothing symmetrical about it (within a half inch anyway), the side radiuses were not the same either. I also talked with a few older enthusiasts who said the lids never fit well from the factory. The best most owners could hope for was that the lid didn’t hit or rub when it was opened and shut. They simply didn’t have the technology to produce the exact same panel each and every time. Even in these modern times stamping dies wear down and shells (the structural reinforcement portion of the part) don’t always mate to skins (the outer panel on the part) in the way theory might suggest so I can’t really answer the question of what the lid measurements are. I’m not sure anyone could.
Here is what I do know though. I know the measurements of the trunk opening on the coupe I’m working on: Across the front it measures 36 3/4 inches, across the back (bottom) is 35 3/4 inches, and both sides measure 31 inches from front to back along the radius atop the quarter panels.
I hope this info helps whomever searched “measurements of model a deck lid” and came across my little piece of the internet. I think it’s mostly important that the lid be functional and pleasing to look at. To any one who’s interested, I’m always happy to answer questions to the best of my experience and ability.
