As I was looking for a cheap seat upgrade, and i stumbled across the fact that my friends car, a 99 Chevy Lumina police package comes with Recaro Sport seats already installed from the factory. These seats almost exactly resemble the Corbeau GTS II seats. I was wondering if i could get these seats from a salvage yard, could i use the Corbeau seat adapters to mount these seats in my 89 LX hatchback, or is there any other bracket that will mount these?
