Well.
Mate Martin who does the disability conversions popped in unexpectedly to sniff around.
Thankfully I could take a break from my desk.
He was always pro-chopping
But sat in the seat with screen up and I could see that maybe if was pushing it with a chop.
So I asked him to take a pic for me so I can see the proportions
The result it seems would suggest holding back on even the 50mm chop for now.
The seat height is fine on the chopped screen.
However, mentally adding the roll bar behind and above the seats somewhat seems to be wrong.
So for now, I think leaving it alone will be the answer.
Leaving more time for the important stuff over the weekend.
Day job has now fully kicked back into gear.
