I am installing a set of bucket seats from 72' Dart into my 72' Duster. The seats were originally bench seats. The tracks on the buckets have different heights, approx. 1". Where is the proper installation for the new tracks, I've read that it's not on the hump where the bench seats were mounted. I know the use of spacers on the interior side of each bucket, but there will still be a height difference. I will include pics of the new bucket tracks. Thanks and stay safe!
