I have made several custom seat mounts. I try to retain the sliders off the old seats but usually end up grinding off the old bases at the rivets and fabricating new ones. I usually will bolt 4 pieces of 1/8" x 1" x 3" lg. flat bar to the floor using the original holes and then set the seat into the truck where I want it. Block it up to the correct height and decide what you need to go between the flat bar and the slider mount holes. Try this before you remove the original bases on the seats you are trying fit since they can frequently be modified or just welded to the flat bar. In the case of separate buckets you may have to drill more holes since the original '67-'68 buckets used the bench mount holes. '69-'72 had add more holes and supports under the floor. It will be a custom fab job...but worth the effort to get the look you want. Good Luck!
