anyone have the part number for that new vacuum pump

[Hammer]

Johnny,

The part number for the pump is GM Part #94669091.
Your local dealer can get one, or you can get it from P & G Chevy. Don't wait 'cause the price is going up slowly. This part was an exact fit on my '91, nothing to change or modify. WVZR1 mentioned in a post that there is a connector available to adapt this pump to a '90. You can also probably make one pretty easy.

Hope that helps.

Here is the connector part # for MY90 or make one and save even more.
