Did they discontinue the diaphram and lid for powermasters?

["Turbo-T"]

I've tried a few places online to find a replacement lid and diaphram for my powermaster.

The old part number is 18013293.

The new part number is 18038511.

The delco number is 18M758.

I go to ac-direct.com or gmpartsdirect.com and try it, none of these numbers work.

What gives? Are these parts now discontinued and removed from the data base?

Check with Eric Fisher.
Goes by turbofish (maybe turbofish38?) here on the board.
I believe he works at a GM stealership.
He was willing to look up some info for me once.

A direct answer to your question.
Yes. I think they have been discontinued.
I'm not letting go of my spare.

Eric confirms they have been discontinued. Really is a bummer. Guess I'll have to hunt ebay or muster up $600 + for a hydroboost conversion.
