Driver Seat installed.
I ordered the seats and brackets early July of this year, I received the brackets within a week.
The seat were backordered about 3 months.

The brackets came with L shaped metal tabs, meant to be bent / cut / welded to fit your application.
Eventually they seemed like more trouble than they're worth, so I eventually used these square tubes:

Cut to 14" long and bolted to the bracket, it worked out well as the perforated holes are spaced out 1" center to center.
The exiting holes from the bench were exactly 11" apart.
The bracket is then bolted to the seat tracks, there are 3 different height settings.
Outboard side is set at the highest (bottom), inboard is set in the middle that gives approx. .625" height difference to account for the floor near the tunnel hump.
It worked out pretty well, I had to cut some of the carpet, Dynamat & foam for better clearance on the 2.5" bolts going through the floor.
A quick drive around 3-4 blocks and I can see my gauges better with better positioning on the accelerator, no more sliding around...
