I’ve driven my ‘97 GMC Safari from the Pacific to the Atlantic and back three times and it’s always been a comfort issue that I can’t slide the seat back as far as I’d like. No longer a problem. (The seats are from an ‘05.) The seat now goes back about 2-1/8" further and that makes a massive difference. Passenger side is next. I have to drive about 4,000 miles this spring and summer.
