Hey buddy, Im kinda new to the Mopar scene. My question is probably in a post somewhere but ive looked and looked and cant find it. I have a stock 1966 Dodge Dart 270 and I cant figure out what the bolt pattern is on it. When i measure it, it looks to be 5x4.5, but everyone is saying its 5x4. How do I tell if theyve been changed at some point? Whats the definite way to determine the bolt pattern on my Dart?! This is bugging the crap out of me. Lol. Please help me bud. I can send you pics galore if that will help. Thanks in advance. Tim
