Rear differential

My new center carrier came and it is for the 373 gears, working on it today and have a problem, gee, that's unusual, OK here it is, the center pin in the carrier sticks out and hits the pinion, I introduced it to the grinder and it no longer contacts the pinion, but what is the clearance between the carrier and the pinion. I am sure that the pinion is spaced out to far and that is the problem, BUT, the pinion bearing was heated to go on the pinion, cutting it off and buying a new bearing is out of the question at this time. I guess I just answered my question. take it all apart pull the pinion remove the bearing remove some of the spacers and start over again. Anybody know the distance between the face of the pinion and the center of the axle shaft???
