I found a pair of nice 6-way leather seats for cheap but the previous owner hacked up the steel mounts. Only one original mount point remains.
I found seat bases/rails (without the spring part under the foam) and I need to swap the new rails onto the seats.
There are four studs welded to the rails that go up through the seat spring cage or whatever it is called.
The nuts go onto the studs under the foam.
I figured out how to remove the two front nuts.
However the rear nuts are impossible to get to by prying up the foam, and it looks like I need to remove the entire seat back to get to those two.
It looks like there are two bolts each side of the back that bolt through the flange that rotates to let the seat go back or forward.
The question is, is there something that I am missing? Is there an easier way rather than remove the entire seat back?
If not, then what is the procedure to get to the two bolts each side of the seat back hinge?
Any help is appreciated.

 

Yeppers! You'll want to unbolt seat from floor of H3 and place on ground in house or garage. Makes sure area is super clean. On each side of back rest/seat you'll locate a fastener/s. You'll wanna remove those and your side seat lower base cover and controls. You are going to have cables, controls, etc. to contend with.

 

Never mind.
I figured it out.
If you loosen the leather cover in the back and push it through to the front as if you are changing the leather, you can pry the foam up and get to the nuts from the back without removing the seat back..

 

Okie dokie.
