Yall Ain't Gonna Bleeb This!

Cool. If you can mig weld.....or even braze, you can do like I did and save the money for the limiter plate.
I did work the body shop for a little while when I was younger also I had a mapp gas kit form Sears ( remember them, when Craftsman was USA!) back in 91. I was looking at that plate last night, looks like they're about 45 bucks with shipping. The only thing I do have is a little torch for sweating copper... I'm thinking by the time I acquired the stuff to do it the old school way, I may be Miles Ahead just to go ahead and grab that plate. And of Course, be annoying enough to ask for some help, setting up a timing curve, that is different from the existing one. I recall you said 20° advance, not 12...
