88 S4, I am rebuilding the intake and cannot find teh spacer/retainer for teh spring on the flappy arm. I am not 100% sure it was there when I disassembled. Whoever did the intake prior to my ownership really screwed it up so it is very possible it was not there. This is at the bottom of the flappy valve arm where the actuator is located, it is installed on the shaft and the return spring fits around it.

I also cannot find a parts diagram for that arm and plate assembly so I dont have a part number.

If I have the dimensions I can make one easily enough, pr maybe someone already has a print file for this.

Anyway, part number, print file dimensions, anything would be helpful. Thanks!
