LOL...that went over my head. I’m old, (an old 39 but still 39) and my arse is dragging from trying to fit a big shifter into a small hole. So clue me in on how that doesn’t bode well for me.

TIA
if you recall my working theory before I actually seen you in physical person with having so much "hot rod" knowledge was that you are actually a 13 year old girl with a stack of her father's hot rod...
