Peter got some seats a while ago and we test fitted the general position. I think I have a plan for properly mounting them now. More on that when the time comes.

I made a template of the left side petrol tank opening, then using that Peter cut a hole in the right side.

The fit is quite good when the tank is properly in place.

Stationary mounting of the roll bar implied tweaking a bit. The top corners aren't exactly the same side to side


Half cm on right and 1.5 cm on left. And this was after compressing the legs trying to install it.
No problem! Just a bit of cable pull. Mounted chain grips to the main bar on the left side to keep the cable in place;

and put a chain holder on the top right side.

I tweaked it a bit by pulling - hard, a bit more, and again a bit more.

In the end it was "much" better, that is to mean nearly the same distance on both sides. I had to take it out to bend the right side main bar a bit outward, just to relieve static stress.
Actual positioning of the main hoop is primarily done by placement of the rear left foot. It is the one with the diagonal (triangulation), which generally can't be tweaked.

Positioning of the main hoop (front) feet is done by tweaking the main hoop.
Despite what I wrote before, it will come out for painting.
