Supercharger Vacuum Actuator

The plastic vacuum actuator for the supercharger has come apart on my 97 Riviera. The part (12371988) is a dealer item, and pricey. Can anyone suggest a generic actuator or a more solidly constructed replacement?

This is the round black ABS plastic unit on a bracket by the supercharger intake with two vacuum hoses and an actuator rod coming out the bottom that connects to the bypass valve shaft in the supercharger.

Since it's the same for Park Avenue Ultras, I'll post in that forum, too.
