Help finding notchback quarter window part

[David Aronson]

I am just finishing the install of the quarter windows of my notchback. There is a small plastic seal/washer that insulates the chrome deco/bolt that goes through the window.
See Picture. I have left a note with Int. Merc. but do not find it in his catalog, nor at the regular suppliers. Anyone know of a source?

If you cannot source it a sleeve of rubber around the bolt and a rubber or plastic washer would work pretty well. A really good hardware store should have such washers.

[Mike Wilson]

Check McMaster Carr, vibration damping bushing, to see if that will work. There are probably other sources as well maybe even your local hardware store.

I have looked for a replacement but they are rubber. These are plastic. I might have a friend 3D build these with his printer. I need four. This part is only used, as far as I know, for the notchback and the hardtop for the cabriolet that has the articulating quarter window.

Look for "plastic sleeve washers".

I think the VW Type 34 qtr window latch uses the same grommets. See below for illustrations. Check with type 34 club guys -- maybe they know where to find those parts: 113-847-205/207. The Porsche part 644-543-491 30 is long gone.

That type of grommet is called a vibration damping grommet you'll find such here: https://www.mcmaster.com/9311k111

By Jove, I think you've got it, Brad. Looking at the West Coast Metric catalogue, there is part #143-320 for the quarter window latches. My guess is Wolfsburg West and others also carry it.

I had some made. I did find something interesting. I have several quarter windows for the notch. I measured the hole on 5 different pieces of glass. There seems to be two different diameters. They are either 10.5mm or 12.8mm in diameter.
So, I had a run of each made. They fit fine. I needed to make a jig to drill the 1/4" hole in them. The process to manufacture these was complicated by the hole so I decided that, to save some engineering time as well as make it a bit cheaper,
I would do the drilling. No need for a VW part if you can substitute custom made Porsche replicas. thank you all for your interest. After all this, I looked up the part in the PET. 644-543-493-26. Listed as quarter window washer. I found them
at Pelican as a special order item. I ordered a set just for comparison. Cost, .25 each. FUN

[Martin Benade]

An interesting challenge, you did well!

[Mike Wilson]

Congrats on solving the problem.

It has been a while since this issue played. The part Pelican listed was NLA. I checked with the Metric and it is also NLA. So, if there is a need for these parts, I have a couple dozen that I will be glad to offer for the price of a stamp.

arenotch quarter window parts still available?

[David Aronson]

Not that I know of.... I have refinished mine and purchased a new set of used quarter windows that had the hinges included. I do have a supply of rubberized washers as stated above. Glad to send a set to you.

I am currently restoring, or at least resurrecting, a cab hardtop. The one I have has the fixed rear quarter glass. I'd love to see a hardtop with the opening windows to see if it is possible/practical to convert to the pop-out windows. I understand that the notch is different from the cab hardtop, at least the rear window is not interchangeable to my understanding.
Actually, I have two hardtops - a completely stripped one that came on my car when I bought it, and a rusted out one I bought for all the hardware. I think quite a few hardtops were ruined when they were propped up beside a garage with the rear bottom-most window frame sitting in moist grass or dirt.
I do have the interior quarter window garnishes for both the fixed and pop-out windows - they are very different. The pop-out latch appears to screw to the garnish itself and not into the top.
What are the hinges in the front like - an actual hinge? Is there a frame around the glass? Has anyone performed this change (hardtop fixed to opening quarter window) - I don't know if it's even possible?
Thanks! This hardtop is one of the more challenging projects I've gotten myself into ...
