seat tracks

Where the trans tunnel begins at the firewall it is about 2.5 inches offset to the right. The right seat will run very closer to the hump.
The seat tracks are not left hand or right hand, just inboard and outboard. One release lever will function opposite the other.
This shows up again in the release cable from inboard to outboard tracks. One cable is tethered to the front of the seat frame , the other is tethered to the rear of the seat frame.
finally the floor studs are a square pattern. 14 or 16 inches, I forget.
Sorry I dont have pics. Hope this helps.
