Kraig - you are correct about the seat and PTO button, the seat being the easiest to see and the PTO button hardest in these pics (but I think it's the only thing on the tractor painted red indicating danger).
Don - well.... the nylock nuts on the gas tanks straps are correct and original.
Jeff - I wasn't aware of a 1" longer steering tube. I'll have to check. How far does it extend above the dash?
There is one in really plain site in the pic with the hood open (and I guess a couple others as well).
Frank - very nice looking seat, and glad to see you have the springs installed the correct direction, and also have the large flat thick washers installed on the underside of the mount base. I don't know how many times I've seen the springs in the reverse direction and those thick washers on the top of the holes in the spring to base mount. Neither makes sense. (As for RMR, keep trying, it helps the mail get there faster).
