where to get manetic autoX numbers?

[limoncello]

Got them at a local sign shop, I think it was around $25-30 for two. The size was 1 foot square if I remember. Did not need a class, since it was for DE. The local DE only required numbers on the sides. I ran a piece of tape along the front edge - didn't know how well the magnets would hold at 100 mph.

As always, check with your local governing body to see what they require...
