Finally an update.
I have finished with the stitch welding inside the cabin and boot areas.
Here you can see how I stitched the sill braces to the floor and the floor to the sills. Also the firewall to the floor.
The tubs have also been fully welded and are solid as a rock.
I modified the seat mount areas for the front seat as I bought a set of Honda Civic ED seat rails. They are the flatest that I found.
Since the rails sit on an angle, front being higher than the rear of the seat. I decided to slope the sill brace so that the rail sat flat and as low as possible.
From factory, the inner most front seat mount is bolted in from the front of the sill brace and the outer most is bolted down on the sill brace.
I removed the outer most mount and made it function the same as the inner most mount via bolted to the front of the sill brace.
The seats themselves needed to have the mounting areas where the rails bolt onto modified also. I had to move the threaded sleeves slightly further apart so as to be able to use the factory cortina floor supports for the seat mounting area.
I still had to fill in the rear floor mounts on the car and then re-drill them in the correct spot.
I got a peice of rectangular tubing to raise the outer most rail as the cortina has one mount that higher than the other.
This is the seat and how it'll be in place.
The seats are OBX Carrera's. When looking at seats I found them to be the most perfect for a normal male shape, that being wider across the shoulders and narrower across the hips. All the other aftermarket ones that I tryed (in my price range) were the opposite.
They'll get re-trimmed once I get to the interior stage
Next up, I'll do the LHS seat mods. I have the rear seat brace to put in place and garnet blast some of the boot area before painting the cabin in POR15.
Onto the undercarriage, WOOHOO!
