Argh. Just what did the do-dad do, shut off the advance permanently, or only 
under particular conditions?

What I'm worried about, is if I'll ever be required to put catalytic 
convertors on the '68 Mustang that I'm going to dust off and start restoring 
next spring. I haven't looked closely, but I don't think there's much room 
under there for one of those things...
 #RW#> Well, there's no smog on the moon...yet.
...and no atmosphere. :(
