There was an old black guy named Richard at the local Short's parts store near Detroit that I went to... he was great... If it was available, Richard knew where to find it...
When the other guys in the store couldn't find it, ask Richard and he knew what catalog to find it in...
There aren't any guys like Richard around any more...
I once ordered a part and Richard said, "I just sold you one of those a few months ago"...
I replied, "This is for another one that I have"...
He would remember what parts he sold me... He was a walking encyclopedia for parts...
