Default WTB: Flappy valve shaft plastic colllar

Hi guys, Doing an intake refresh and I forgot to take off the white plastic collar that sits on the bottom of the flappy shaft on my '88 S4. Of course, it is nowhere to be found at the PC's shop or anywhere in between.

Does someone have a parted car or intake that can sell me one. And also the shim/washer that sits on that end of the shaft.

Thanks in advance!
Luis

Flappy Spring x1 928 110 658 01
Flappy Spacer x 2 928 110 650 00
Flappy Circlip x 1 N 012 439 2

I have the circlip & spring but the spacers are NLA - on the list for 3D printing

Thanks Roger. Do the shims/washers that go on top and bottom have a part number? Don't see them either on the diagram or your listed numbers.

Does anyone have one on hand with some dimensions so I can try and shape one?

--->EDIT: I think what you are calling spacers is what I am calling shim/washer.

What about the plastic collar/spacer found only on the bottom of the shaft. Does that have a PN? Not on the diagrams.

Flappy Spacer x 2 928 110 650 00 - these are the two spacers/washers you need - currently NLA

Thanks Rog but I want to be clear that what I am mostly looking for is a plastic ring that acts as some sort of spacer and found only on one side, the bottom, and is hidden from view until you remove the spring. The spacers you provided the part number for are very thin washers, almost like a shim.

Here are pictures of the plastic spacers and the torsion spring - hope that helps.

Just so we're all on the same page, which # piece are you looking for?

Roger, Rob. Either of those spacers are a slam dunk for 3D printing. I could have a prototype for either of you to check out next week if, Rob, you could scan these.

I would lean a little bit more towards turning them on a lathe than 3D printing, if they need to fit tightly in the bore and have a smooth running surface on the shaft. I guess you could print them and then run a drill bit through the center and spin them in something to sand the outer surface.

OK that pic makes it easier. I am missing #2, which is the same as #7. And also #1, which looked to me when I removed them, the same as #3 and #6.

Nate: I don't believe the plastic spacers would need to have the intricate pattern on the back, as seen in #2. It looks to me like a flat surface there would pose no detriment to the functioning of the shaft. Then it should be fairly simple to 3D print, no?

Karl, The spacers' only 'critical' dimension is the ID where the shaft fits. Take a look at them here. They just are placed one against the other and the OD loosely (if that) contains the spring within the 'spool' the spacers form (Dwayne's pic).

There is the problem and as I said the parts are NLA. If we could get a sample part we could have them made. Maybe Mr. Edwards has the dimensions.

Here the dimensions of mine. Needless to say since I am the instigator of this project I am willing to put up some funding to get it done... (sorry for the huge pics...)

Thank you all!
