Do you have the booster? I’m not sure what type was correct for this car.
If you have a booster, there are a couple of guys who can do refurbs on them. If not, then identify which one was correct for your car and go from there.
Are you planning on installing it yourself?
I removed mine since it leaked inside the device after it was rebuilt with a kit at a local shop, not by a specialized booster repair shop. I don’t expect to replace mine anytime soon, either.
