8. too high with that big transmission hump in frame. Welded in 2 "S" shaped brackets to lower the center rails

You can see in this first pic I hoped to just cur the old frame to length, sit it on the frame, bolt it to the Jeep base, and go, but it sat way too high. This set up wouldn't fit under the steering wheel.

The Gladiators have a very high transmission hump that goes way up into the seat. But I wanted to keep the bottom of the frame so I could keep the seat adjustment mechanism and the original bolt up pattern...So... some more fabricating...

You can see I welded in two "S" brackets to the two center rails (the flatest looking pieces welded to the crossbar).

This lowered the seat 3 inches. This allows the side of the seat to sit on the frame, and the center of the seat to "down into" this frame, and just touch the transmission tunnel. I drilled and bolted up the front,  and then back to the frame.

So, a nice seat with modern seat belts for $65. (Ok, in practice it STILL sits a bit high but not bad at all).

Here is what it looks like now in the cab. You can see how the seat sits into that frame front section now, on those two S brackets. Actually I was a 1/4 inch off, if you look closely you can see the seat actually touches the transmission hump and pushes up a little bit. But I need it as low as it can be so that works for me.
