The same goes for the auto parts business. All of us older parts guys that started in the mechanical field and moved to the parts field are slowly leaving. I watch all the younger folks hired in fold when confronted with a old car question. Most places don't even use catalogs anymore, they rely on the computer cataloging which isn't accurate all the time. Freaks them out when I grab a catalog and find the part. I try and then teach as much as I can but I often think of what's going to happen when all the people with this knowledge retire. And the new younger generation relies on their computors for everything when the guy with the early car needs info. That is why I am teaching my boys and daughter everything I can while I can still remember it.
