i was wondering if anyone has replaced there vacuum modulator? if so i was wondering if you can tell me the part number of the modulator and what auto parts store did u purchase it? recently i went to auto zone and i looked at the one listed for the 95 bonneville se and the modulator is much smaller than the stock one, iam not to sure if this would fit or work, has anyone replaced theres?

Haven't replaced mine. Do you have harsh shifts or something? Interesting note, at least on the 93'*, the modulator is made by Holley.

The AZ replacement should interchange no problem. An aftermarket vacuum can for any automotive application may not be the same size, and can still be calibrated the same.
