I was rummaging thru my gear sets last night thinking about a gear change for the Dart.
I have a 3.91 open chunk that has no number on it. (489-741-742)
I was told they were the older units and were typical to the 742 cases. Anyone have any info?
I'm going to roll a clutch posi unit into it and want to make sure it doesn't have the small diameter pinion.
The Dart has slicks and the 340 makes decent power, I don't want to waste time with something that might break.
