I am chasing down a vacuum leak.
I replaced a worn late throttle body with a NOS early throttle body. A throttle body rebuild post I came across shows a brass ring seal and a seal that goes around the shaft on the end where it enters o the throttle body. Neither of the TBs I have have the brass ring or the seal. Are there supposed to be a ring & seal on each side of the TB? Are these available? Are they necessary? Are they the cause of my vacuum leak? I can't detect any play in the shaft. Picture I found that shows the brass ring  Pic of a post I found that shows all the parts:  |

I believe the brass bushing is an aftermarket upgrade. The shaft runs bare on the aluminum housing which will wear out over time. There is a seal on the 1.8 that goes here, not sure if they all had it.
