I put some from a 1990 in my '74. I retained the stock brackets. I cut a 1/8" piece of plate that was 17"x17" square. I stitch welded the stock brackets to the plate. Then I drilled the mounting holes for the seat through the plate and bolted them up. I had to modify the lift lever for the back of the passenger seat so that it could recline (still fucntional and works well). Keep in mind, that the new seats will make you sit about 2" higher than your stock ones because of the differences in mounting (I like sittin ghigher anyway, better line of sight when wheelin'!! /forums/images/icons/laugh.gif ). But if you want to retain you stock mounting brackets, that is the way to go. I can post pics if you are interested. It was a VERY worthwhile swap.
