massive reconfiguration time again.

So a little technical help needed here...
If anybody remembers I got those Spirit of 76 buckets to put in the duster. Again still trying to figure out the brackets just a little bit and now I'm going to use them. I had a friend help me walk the bench seat out just a little while ago and I went to put the bucket seat bracket in where that bench bracket went and I was all this ain't going to fit?? It was sticking out too far close to the door and also it was humped up too much on the out side? Then I noticed under the floor there was holes just inside of those humps for the bucket seat? I'm assuming that's where the line up holes for bucket seats are?
