I can't access Ausubaru.com/forum via my phone (that I'm on now), but if anyone is using an old version of internet explorer or Firefox you'll be able to access the address above and look at more than one page a day.

 

On that site one of the members (Bantum) has posted details of these rings for 3D printing. Follow the link and I believe you down load the details then go nuts with the printing

 

Cheers

I found a couple, and a broken one. I will make a model and drawing so you can check the dimensions.

 

They look like the thicker one, at first glance.

The inside groove measures .288"

The outer thickness is .510"

The flange on one side is about double the thickness of the other.

 

Does this sound like the part you are looking for?

My buddy is printing them now on his printer, I hope they work!

Will post picks when I get them...
