First, I appreciate this web community and have found the same helpful communities for my Bronco and TriumphRocket.

I am progressing on the 56 to the point of needing to set the front bucket seats and seat belts. They are out of Lincoln coupe and look perfect. I have an email out to a seat frame builder to see if he has anything to offer.

If not or if price becomes an issue, also preparing a home built solution. As you guys know the outside bench mounting is 1 1/2 lower than the target inside mouting location. The front of the new seat mounts slant downward at 45 degrees and extend 1 1/2. So, raising the seat height 1 1/2 on the inside and 3 inches on outside and bracing under car with flat bar for seat and seat belts is an option. The other option is to pound down the inside floor, with under bracing to avoid raising the seat the 1 1/2 required in the first option.

If your build required anything close to what I am facing, I would appreciate your advice.

I measured the difference in height at 1-1/4", but I guess that's a small detail, as you need the same approach for either measurement.

For the outside mount, I built a piece from 1-1/2" square tube with some brackets made by cutting up some of the same tube - the brackets bolt to the original seat anchors front and back.

I made the inside mount from 1-1/2" wide x 1/4" thick steel bar. Since my seats had seat belt anchors in them I wanted the rear of the inside mount to be anchored to something sturdy. This was accomplished by extending the inner mount to where the bolt went through the floor brace just behind the seat. On the front of the inner mount I just drilled a hole and mounted it through the floor. I put a brace on the bottom of the floor made from the same 1-1/2" x 1/4" steel bar.

Before you commit to the height of your mounts, make sure the bottom cushion of your seats will be right. My seats could be adjusted quite a bit lower than a stock seat, so my 1-1/2" outer mounts were fine. If you need the seat lower, you'll have to cut a tunnel in the floor for the inner mount.

The other thing I had to do with my installation was to do a little cutting on the transmission tunnel so that the seat could be centered behind the steering wheel.

Thanks for the information and confirmation of approach. For the door side outside mounts,because of the slant of the front seat mount, I think I need to box the ends of the 1 1/2 square pipe to allow for the slant, and either weld in a bolt to allow me to then mount the pipe through the floor vertically, or mount through floor and brace accordingly under the floor.

The 1/4 inch plate on inside mounts should bring seat mounts to level. This will require shaping the floor, and possibly a reshaped divot in the floor to mount.

Thanks for mentioning the need to center the driver seat to wheel, as my initial impression was the seat was biased towards the drivers door.

Until I power the seats to hopefully lower them, my concern is adding seat height.
