1998 C70 Air pump mount bolt same as window motor mount?
 

Is this part: Volvo Air Pump Rubber Mount (850 C70 S70 V70 960 S90 V90) - Genuine Volvo 1275534 | FCP Euro the same one used to mount the window motors? I thought I broke a regulator in my 1998 Coupe, but turns out the rubber just separated on the isolating bolts used to hold the motor to the regulator. I temporarily replaced them with long bolts and washers but that makes it make a hollow annoying sound when shutting the door. If this is the same thing or can be used as such, that would be great so I can repair this thing right. Anybody know?

Really? Nobody has any idea?

nope. won't work. Have you tried some small rubber grommets?
