Nope, the center section of the M20 didn't change at all through the years. Sounds like someone sent you gears for the wrong axle.

No they wouldn't. You need gears from a CJ. A YJ has reverse cut gears as do many years of XJs. The TJ has a different pinion, which is what it sounds like you got.

The CJ, Scout and early Bronco Dana 30's are the long pinion std cut style. Most XJ and all YJ Dana 30s are short pinion and reverse cut. The last couple of years of XJ had the short pinion std cut front Dana 30 like a TJ wrangler.

You can't just use a used pinion to replace the one you had. Ring and pinions absolutely have to be used as a set and kept together. They are lapped together as they are manufactured and if you use one pinion in place of another it will lead to a very short life for both the ring gear and the pinion.

You need a CJ Dana 30 ring and pinion set. They can be used but they must come together.
