When does money outweigh sentimental value? 1968 notchback build thread

Actually, before I took my kids for a ride, Sunday I jacked the car up and found rear pinion seal leaking quite a bit more than I thought. So I pulled the pinion nut and yoke and had a bunch of garbage in the seal lip and the back side of the front pinion bearing. Whatever it was, wasn't magnetic. Just kind of dirt and grimy. So I cleaned it, got it all out of the seal lip and reassembled. Of course, when tightening the pinion nut, I missed my mark and over torqued it a bit. Just enough that there's now a little hum in the rear end. That's what actually prompted my new center section purchase but figured the rearend is 40-50+ years old and never been refreshed.
