Hi all - 71 510, stock w/ 3.70 diff. Took it all apart, cleaned it and reinstalled crossmember with diff still out. Now want to put in diff from the rear, but don't seem to have clearance without dropping the crossmember again. Is this correct? I'm trying to put the diff snout into the crossmember and push it forward but the rear of the diff hits the spare tire well and I can't quite get it back far enough. Do I have to drop the crossmember again ? That's a real pain because this car is on a hill, and without the crossmember in there's really no place for jackstands. What's odd is Hanes manual just says unbolt and pull it out - no mention of crossmember or clearance issues. WTF ?
