Vent Window Nylon Repro Project
#1

I got a vent window nylon piece out. They are a bit interesting in their design, as they are split from new. As the piece wears from age and gets stiffer in its mount, turning the vent window open actually pries the piece open a bit causing it to jam when it hits the metal, resulting in the "45°" window, instead of it opening fully. Of course if it's really lacking lubrication, or is fractured, any number of things can happen. I even saw a car once where the vent window was stuck open at about a 90° angle.

The trouble is that the slot can't just be eliminated because that's what helps regulate the friction holding the window in the desired position. Without it, that would be too hard to adjust. What I have done is rounded the edges a significant amount using spline curves. This seemed to help significantly in my test piece. Likewise the top flange has a standard round. To aid in 3D printing, I eliminated the tab on the bottom of the piece, as it really should not be necessary for the piece to stay in place.

I have made an eBay listing here: https://www.ebay.com/itm/255816359330
Price will be $9.99 (+ shipping) for a pair but if you want to pre-order them now it's $1 off... (trust me you want to replace both). I want to get things validated before shipping them out.

If you need more than a pair, just DM me and I'll quote you based on how many you need. For example, for 16 I can do $49 instead of $80, with shipping included.

If you're interested please write below. Likewise if you have any suggestions.

Great timing! I've been fretting for the last year just how to solve this very problem. Thank you for this project. I just ordered 2 pairs.

Any pictures of the finished 3D print? Did you do them in Nylon?

Did a bit of prototyping and I have a design I'm happy with. I also received a number of pre-orders, with a fair number of units going to the Switzerland Packard Club.

The pieces are solid nylon, printed with Multi Jet Fusion technology which provides greater strength and dimensional accuracy than traditional 3D print methods.

Here is a short video:

Here is a tutorial of how to install on a 2dr. The 4dr instead of removing the hinge screw, there are two screws above the vent window to unscrew, then lean the window asy towards the interior of the car (with the door still open, of course) and remove the two screws on top of the window, then the pin can be pried up out.

When installing, note the image below for the correct orientation.

The rear windows do not use these. Rear windows don't get stuck the same way the front ones do. If they are too hard to move, they just need some grease.

Thank you. I’ve not done any significant work on my 1956 but I have been trying to get parts as they become available so wanted to be sure how many were needed. Now I know!
