These couple of hard plastic parts live down in the mechanical advance portion of the stock distributor. The picture shows the biger ring in whole as well, but it's old & brittle and I don't want to use it.

Can these parts be sourced from anywhere? Any help would be appreciated.

I haven't been able to find any.

Can one of our Uber Genius vendors in residence recreate out of Delrin or similar?

Specs for the brave soul who attempts?

I have a extra distributor that came with my car that should have the same pcs inside. You could have it for a couple bucks if you want it. It's in good condition and tight. PO had bought it to replace the on in the car but the car is a 2.0 D-jet and takes a different type so I just rebuilt the one that was in it.

I would love to, but my car is a 73-2.0L w/ D-jet as well. Which distributor do you have? I am wondering if it would have those exact pieces in it?

It might. Mine had already been switched to electric advance so I don't know what they are suppose to look like stock. You said you needed pcs for the advance on top correct?
Heres a couple pics
Maybe someone else on here might know for sure if it would work.

I'm sure I can have them made, if I could get good dimensions off them and enough people to want them. Not worth setting up the CNC for only a couple parts.

No problem, I'll measure & post later on today.
I am not if I can wait for the outcome, but if & when they become available, I'll grab some.
