68' Valiant 4 door

they sent me a shifter ball with a button. ok temp. i have the parts to make a pistol grip handle and think i've figured out how i want to add a button to it.

got it off the stands and moved but that's it. my upside down left handed welding is good as ever so it took a little longer than i hoped to finish the hangers. ended up going to work today so it will be next week before i get time to try it out.
.. Shelved that and put a simple incognito on/ off toggle on the RH side at the front of the base of my drivers bucket.
is that to shift in/out of it or to set it manual/auto? are you running the computer?
