I purchased 70 challenger apart. Drivers seat is original. I got two other seats. Now getting seats recovered and found out seat tracks are different. Drivers seat tracks are 3/4 of inch lower than passenger seat. Is this normal. In pic number one and two are four inches below board. Number three and four are 3 1/4 inches below board. Bottom line is passengers seat 3/4 inch higher or wrong tracks if so need pass tracks?
