Bit more work done today.
I've attached a couple more pictures, might make more sense of where I am thinking of my chute handle. I have mocked it up with one from a fire suppression system, I mounted it infront of my brake lever, so it's a pull chute......pull brake.
Also sat in the car and tried the shifter, Oops... hit the axle when I pulled it back for 1st, I then realised that once strapped I'd not be able to shift it forward enough for reverse or park. Time to get thinking
out with the woodworking tools and some ply and a temp handle fab'd to test operation. Took a couple of goes but it works, just need to sort some cable for operating the lockout, and get a shifter made. Not sure a wooden one would pass Tech inspection
Oh and the views not bad from the seat.
