I’m shocked !

I think it's like that with about any kind of wear item parts for our old cars. I had to replace the brake shoes and wheel cylinders on the back brakes of my 71 Challenger the other day, and the local NAPA was the only place that could get me shoes the next day. When they came in, the box looked like a barn find....lol. Also, it may be because of the pandemic, but there is a shortage of parts for cars, appliances, machinery....everything right now.
