[DeTomaso] Dizzy gear blues - Dan or someone help please?

[adin at frontier.net]

NPC but Pantera interest.

Windsor motor, MSD dizzy, brass gear.

It appears the teeth on the brass gear are about 1/2 worn through -  
this means the wrong gear for the cam, correct?

Do I replace w/ steel or iron gear?  Is this a Napa item?  Ford item?   
Or am I staying home next weekend?

Next question:  how much damage, if any,  do these brass filing do to  
my motor?
What next?

thanks,

David, paniced in zip code EIEIO.
