Best Place to Purchase a Base Plate

Personally, I wouldn't be comfortable either buying or selling a used baseplate for safety reasons. Several years ago, my HHR burned up due to a wiring short in the heated seats. BlueOx indicated the heat from the fire may have damaged/warped or otherwise compromised the safety of the baseplate and wouldn't warranty it at all. They also specify that the warranty is voided if the baseplate is welded on the vehicle....just food for thought...YMMV....Dennis
