Snap On Dealer

I’d definitely contact Snap-On or your local dealer. I’ve gotten some spare parts for my old compression gauge and other stuff online. Some local dealers are good about this and some aren’t. I still have a few things left over from when I was a Snap-On dealer (1978-85) that I keep in the same little red bin that rode on my truck, and I use them from time to time. It’s a different world since they franchised their dealers, however.
