I'm as tall, a hair more, I put the seat back until my right knee can clear the corner of the center console stuff, by the AC switches I think, so not quite all the way back. Yeah, half price is the time to try things that might not work. Pay attention to if the rails mount to the floor or the sides of the car or transmission tunnel (I know it's not RWD, but whatever the center bump is called). That will tell you if you need to move on to the next used car seat or not pretty quick. Best of luck with the seat!
What deadening will you use? Tsunami? Dynamat? Home depot tar paper?
