The problem is I'm 6 feet tall and need the seat all the way back and my wife is about 5 feet tall and needs the seat all the way foward and up in the back so the seat sets level. So what I did was install 1" spacer blocks under the rear of the seat which works out great for her but not so much for me.  Has anyone installed power seats in a Challenger? If so what did you use? 6 way manual seat bracket would be good also.    Kevin
