Quick update for anyone wondering about these seats
I have a 1983 280ZX and I threw in some corbeau GTS II seats with shaved bases and a corbeau dual locking slider on the driverside and a single locking slider, on the passenger side. and corbeau bolt in seat brackets. I'm 6 foot tall but have a 30" inseam so you can imagine my torso is a bit taller than normal. Anyways they sat higher than stock and I ran out of head room and had to drive kind of slouched with the T-Top sunshade removed.
To fix the passenger side I removed the sliding rail and bolted the bracket straig
