Bench to bucket conversion, need help please

I did this conversion on my Duster, piece of cake. I made plates to reinforce all 4 holes and tacked them to the floor. I forget what thickness plate this is, probably around 1/8".



Also, if you bought the Summit seats you don't need any kind of bracket adaptors. I just bought Summits mount kit, but all that really amounts to is some 2" aluminum angle and some bolts. For an A-body and those seats, the extra holes don't matter because they get used on the "smallest" setting anyway, basically just making a "C" out of the angle. The holes in the floor don't line up directly over center on the holes in the seat, but the width is close enough to manage with the 2" overlap. The length was a little further off, but that doesn't matter with the angle.

I'd just buy some 2" x .125" angle and make the brackets myself. That way you could make them steel brackets also. I'd consider lowering the seats from the 2" added height too, but on a 4 speed car like mine you can't really lower them much or the driver's seat will hit the 4 speed hump. On an auto car you could probably have the brackets be about an 1" tall and have it work great, the seats sit you up pretty high in the car.

Here you can see how close the driver's seat is to the 4 speed hump
