Anybody with a standard c&c seat, how far back to the top of the lumbar support from the dash, 2015 roadglide? Not the sport tourer seat but any of the solos. I'm 6'-2 1/2" with 33" inseam and trying to figure out if I need to order stock, 1" or 2" back. I'm going with solo and passenger pillion, probably leather with gel. Any help would be appreciated. Thanks!
