I have dealt with both, the off set one is used for the high gear ratios like 2.71 and 2.45 The pinion gear is huge and that is why there is a offset. Mike has the track loc for the offset. We are thinking about doing a thread together on this.
I will be gathering notes and info on all I have and learned the hard way, between you and I and the info we can gather from here and the world web we should get a good help thread going boss :usflag:
