I,m installing a new dash in my basket case 69, but the old wiper switch does not line up to the plastic screw mounts on the dash. Am I missing some other equipment? Or do I have the wrong switch. There are three metal mounting holes on the switch and three plastic mounts on the dash, but they don't line up. Also, if it did line up, the metal on the switch would be about 3/8" above the plastic mounting holes. The old dash measures the same. Unfortunately, all was disassembled when I got it.

Thanks

I'd say you have the wrong switch. :(
