Just realized how old I am...

I owed a parts store in the early 80’s and I kept a set of 426 Hemi valve cover gaskets in stock for the occasion when someone asked for a set of dodge VC gaskets and state there all the same. You should see the look on their face when I thru them on the counter! At which time I would ask them for a year and engine size. Kinda would shut them the hell up.
