The speed of a semi truck is determined by the powerplant, transmission, and rear end gear ratios. Take three trucks.. let's say, in this case, three Freightliner Classic XLS... they have the same motor, same transmission, but different rear end gear ratios. One truck has 3.36 rear ends, one truck has 3.70 rear ends, and one truck has 4.11 rear ends.. the truck with the 4.11 rear ends would be the slowest of the three, but better suited for particularly heavy loads. The truck with 3.36 rear ends would be the fastest. The fastest truck I've ever driven was a Peterbilt 389 with a Cummins Select 600 horsepower motor, 13 speed Eaton Fuller transmission, and 3.25 rear ends. It was capable of doing over 140 Miles Per Hour.

68 to 75 nova, the same body style will work.
Yes, from 1982 through to 1992 the rear ends should all fit. The are all the same generation car.
yes they all have the same rear ends
At the Chevy garage they insisted on "automotive technicians", but yes. They are all the same name for a mechanic.
yes
begins and ends at the same point
Yes the rear ends on those 2 will be a direct swop. If it is a 4-wheel drive then you MUST make sure that the gear ratios are the same.
That question can't really be answered as asked. Not all .38s assemble exactly the same way.
In automotive terms, yes.
