The play on the pedal was getting too much. And I had repaired it twice prior.
So got a rare spares one in.
Have a look at the side by side below

You can see the two spot welds that join the pivot to the pedal are such that the foot that bolts to the floor is not set square like the left one. Left as it it hit the kick panel.
Also in the below you can see the difference in the angle of the lever (and my previous repair)

Not sure if the new pedal is out of spec. (First reaction). Or my pedal is out of spec. Or both!
One way to overcome this:
I ended up separating the two spot welds from the pedal, aligning the pedal straight. Then i added a section (in red) both sides and bottom ( U shaped) welded in. How do you do that with a rubber backed pedal?

This added piece is to extend the load to which the stress can transfer. I don’t think the two spot welds so close to one end provides the strength as that’s how mine failed previously. Plus I’m running twins so likely a bit more stress than a single.
Second thing I did was grind the spot welds on the pivot (green arrow) and turn the linkage lever to align with the old pedal angle and re-weld.

Tested, aligns well doesn’t foul and linkage works to full throttle opening.
Key learning: check your replacement rare spares pedal against your old one before you fit it. Mine were chalk and cheese.
