Installation Notes

Verify the vehicle year, make, model, and mounting position before installation. For the 1999 Oldsmobile 88 application, confirm the driver's side, subframe-mounted, hydraulic-type configuration. Compare the original mount to Pioneer Cables 629000 to confirm the housing shape and mounting points match the vehicle.
