I have a local supplier that has been in business since about 1946 or so.
They have undergone changes in ownership, etc. and now go by the name of
Baxter Auto Parts.
The real value of this vendor lies in the collective knowledge of
those grey haired counter elves. That, and those old paper catalogs under
the counter that they drag out every time I walk in the door and cross that
cracked concrete floor into that dimly lighted building. Hoses and v-belts
hang from the exposed rafters. So, when I come in with a rubber part like
those molded hose ends, it is an even bet that they are familiar with them.
Can't buy that knowledge, it is either passed on or dies with those
grey hairs.
Will Advance Auto Parts Or Rock Auto and their computer nerds ever
compare with that human knowledge base? I really doubt it.
So, are those rubber bits still available? Depends upon where you
look, I guess. Yes, I feel lucky to have connections like Baxter Auto
Parts. And I support them every chance I get.
