In the middle of hay hauling last week, I discovered that the brake light switch on my 1960 GMC 3/4 ton was sticking.
We managed to free it up with some WD-40, but I don't know for how long, so I looked it up online without much hope of finding one.
Several places have them in stock, with the cheapest one being about $5!
That is not what is bothering me today though.
This is and it is probably not what we need about now:
