memikes right all the way around...I've forgotten the rotor before too.:oops:
Hmmm....well it depends on what you have there...but a parts store with a speed shop area might. I'm really not sure about someplace like NAPA but PEPboys might. You can buy them online too.
You can test it to see if it's good too. Just run a search on mallory ignition and i"m pretty sure there's a procedure in there.
