My parts manual has a permanent research spot on the kitchen table....
Yep, a good example is when I was trying to figure out if a steering wheel from a 1977 Charger would work in my 1978 NYB with a T&T column. The parts book says C-body only for the steering wheels for the T&T column cars. They probably just grabbed the steering wheels off the shelf and just compared them side by side and said that won't work...... I had to machine the back side of the Charger wheel on a lathe to get it to work on the NYB with the T&T column. No problem.
I said it would work but did anybody listen? Noooooooooooo.........The question at the time.... was the spline and the diameter on the steering shaft the same for both steering wheels and if the slot for the T&T locking lever was there and in the right position, etc. Some people on this forum said... no way.... and some said maybe.....no one knew for sure.
