Back then, mechanics took enough pride in their work to demand enough information that they could actually fix things. That sort of attitude started going out of style about 3 generations ago. Now, all we have left for the most part is a bunch of "wheelbarrow mechanics"- - - -guys who roll a wheelbarrow full of new parts up to the job, and start swapping stuff until the problem goes away. Once a part is installed, it's got to be sold- - - -whether it was needed or not!
