Ok, but I want to know the brinell of your skull. ______this space for smile emoji. (on backorder)
Carl, it's me, your buddy. Would I "steer" you wrong?
Where our debate has gone of the rails a bit, is from attempting to come at the issue from two entirely different perspectives.
1) Late '40s/early '50s GM design.
2) Everything which you have brought up.
While you have brought up some very pertinent and valuable technical information, many of them do not apply to what GM did from '47-'55.1 with the steering arm bolts/nuts.
You need to buy you an AD in original condition for 2 reasons.
1) So that you can hang out with the cool people.
2) So that you can witness firsthand the many peculiarities which you don't see on later models. I find myself asking myself, "Why'd they do it that way?" Most of the time it was due to the limited technology available at the time, and cost saving constraints.
I will say this. There are numerous peculiarities on the ADs (these steering arm bolts/nuts included) which would definitely be improved upon by many of your suggestions.
