We considered power windows but Troy wasn't excited about it. If we had done it, we would have used the stock '59 riser mechanisms and adapted on Ford power motors (see here
These Ford motors have the same gear pitch as all old window risers so all it takes is welding on a mounting tab. NO after market riser mechanism can compete with the stock factory ones. I show how I did this on my '53 Chevy pickup. Then all you need to do is wire in a set of junk yard or repro 70s Chevy chrome switches (see here
See the master 4-switch in front. single swithch in rear on my pickup.
Results in a much better and cheaper power window than the flimsy Chinese power riser systems.
You are correct, if we had gone the column shifter route, installation would have been much more complicated. I think we will take off the '59 dash mounting bracket and cut out the front of the mounting slots so if a body slams into it the the wheel, th bracket will slide from under the screws and activate the internal collapsing joint. might as well employ all the safety as possible.
