I got the pedals figured out (still need to weld in the gas). I had to put a big jog in the brake pedal to clear the steering column. Everything feels pretty comfortable though so I'm happy with how it all came out.
I am sure that your arm will be more than strong enough. I had to redo mine anyways because the a340 kit pushed the cable out too far which made it hit the front driveshaft.I would have completely remade the arm but if it got any thicker the nylon on the nyloc would barely have touched the treads. I guess remaking the arm and getting different nut would have been a better approach. fuuckk it
