Got some goodies in the mail.
With some help, managed to repair the high fan speed. Still missing the medium high setting, although if I was a betting man I would guess its the same issue: cruddy 70s electrical connectors. I also “fixed” i.e. found what I did with the parts for my neutral safety switch, and learned some interesting things.
1. Gm used the same mechanism on all the f bodies from 1971-1981 automatic cars
2. Nobody makes the parts, not even the critical plastic bushings. Wut. All the other bullshit they make... Thinking I should get the dimensions so I can make a cad file for 3d printing. If only I actually knew how to do that.
3. GM were massive cheapasses. F bodies in 1970 were available with column shifts, but it was almost immediately discontinued. They kept the exact same mechanism with a massive floor linkage for 10 years. Observe:
The whole column rotates, for no real reason other than there was a lever breifly attatched. They made hundreds of thousands of these in that period (maybe over a million?)
Fantastic as always.
By the way, my chosen wheels were backorderd do to the caronabeetus and thus I ordered snowflakes instead. I still may get turbines at some point, especially as a set through classic only costs 550$ on 35% off which they run all the time. Center caps are nearly 1/3 of the price of the wheel, but I already have those.
