I've got a 1975 Chrysler 45 model 454 and I think that I need to change the points. I only get spark on one cyllinder. I haven't pulled the flywheel off yet but I have a new set of points anyway. What is the gap and is it hard to do? Also, is the flywheel bolt a regular thread or is it reverse threaded and what is the torque? I wish I had a manual, it'd be so much easier...<br /> Cheers to anyone who can help with this info..<br /> Thanks...
