I noticed a '56 Merc drip rail seems to go around the front, Fords too. How many years did that go on? Any purpose to it?
That was back before the considerations of aerodynamics. It probably saved a few pennies in the manufacturing or assembly process or it wouldn't be there.
I wonder if there was a marketing gimmick: "Keeps water off the windshield while backing up and looking forward!" Noticed it while watching Highway Patrol.
I would guess it was just the manufacturing process. The drip rail is sandwiched between the roof panel and window/door surround. The three are spot welded together. And as said above, no concern for aero back then.
I always assumed it was when they went to curved windshields, to keep water from dripping down the A pillar into the car? Sent from my SM-G981V using The H.A.M.B. mobile app
Seems like most of the '50s era Fords had them. I got an idea that it was structural as much as it was a drip rail.
49-52 Chevrolets are famous for this. runs right down the drip rail into the car once the rubber gets old. water sits right where a body mount is and rots it...... 50 - 52 Chevy hardtops have a drip rail... I bet they don't have this issue.
