The BMW 507 Ultimate Build Thread!!!

[A12pilot]

Up next, functionality. I need an internal door to block off the fresh air if I need to. Which I find funny since this is a convertible and I doubt I’ll ever had the top up. But, everything has to work and I can’t have a box that’s just there and not have it work!

The door is cable actuated and mounted inside the plenum via a bar which the door is welded to. I formed the arm and then installed a few beads on the blocker door for rigidity. Nobody will see it, but I want it to look good in case I’m ever up for the elusive “Best Heater Blocker Door” award. The door arm rides on nylon bushings with a brass insert which should provide years of trouble free operation.




I then positioned the door inside which allowed me to trace the pattern onto the plenum so I could install the weather striping seal.






The result is a lever operated door that seals the incoming air when needed.

Here’s it is in position with the updated cowl intake which is now identical to the factory intake inlet.



That’s just a window into the insanity. Just imagine the lengths I went for the glove box hinge latch! Oh don’t worry. I’m a lifetime member of the “Looney Tunes” division of the Henry Ford Clinic.

More to come!
