Looking at the Pelican catalog, it looks like the Tarett and Weltmeister sway bars interchange:

Tarett Engineering Fully Adjustable Hollow Sway Bar, 22mm, Rear, 911 & 911 Turbo (1978-89)
Weltmeister 22mm Rear Sway Bar Kit, 911 (1987-89), 911 Turbo (1976-89)

Unless you are married to having it look stock, you could always go with a Tarett, Smart Racing, TRG, etc. bars and have a adjustability, which the Carrera bar won't have.
