Is there more room on the drivers side then passenger side? (seat install)

even a non factory bucket car has "dimples" in the floor pan where the bolts holes would be located. also factory bucket cars have added support on the holes of the floor pan to beef the floor up where the seats mount. On my duster, I found the factory dimples in the pan, drilled them out, then took plate steel and drilled them to match,then welded the plates to the floor pan. Then used a set of power leather seats I picked up and built my seat framing to match the bolt pattern of the floor.

There is a link in my signature below to my dusters build thread and I covered how I did the install and with pictures too. maybe you might want to give it a look see and it might help give you an idea of what I am talking about.

might take you some searching though as there are quite a few thread pages lol.
