It's really a very easy thing to do, yet people act like it's frikkin brain surgery. Just find you a copy of the Mopar Performance engine book and you'll have step by step instructions at your fingertips. They're still out there, you have to look. The latest is the ninth edition. Tells about taping a vacuum gauge to the windshield to find cruise vacuum, how to adjust, how to curve the distributor. It's really very simple. I've preached for YEARS on this forum that the first thing you should get is the MP engine manual but nobody ever listens. If you cannot find one, find a friend or member here with one and see if they will scan that section for you. It's VERY EASY to see how to do this when you can read it in black and white from the Mopar manual.
