I'm having new covers put on 16655's seats, and I'm really wanting to have seat heaters installed at the same time. Unfortunately, the area on the seats where they'd go is roughly 8" wide- and pretty much EVERY seat heater that I've found is 10-11" wide, and you can't trim down the width.

Has anyone else had seat heaters installed? And if so, what kind did you use and where did you get them?

Thanks!
