I have a 1995 GMC Yukon vin K. This is a replacement engine (used). I need to restab the dist. I have a very rough idle and I beleve the dist is off. How do you point the dist with #1 at tdc? The wires could be anywhere around the cap correct? As long as #1 goes to #1? Please give me a clue. Right now #1 and #8 are front of the dist. not exactly across but somewhat. The module is closer to straight than 1 and 8.
