Hi all, I have a few broken teeth on the upper spider in a 8.5 posi unit in my 73. I was hoping to possibly get some suggestions on the best path forward from people with more experience as I've never done any diff work (taking the axles out was the furthest I've ever gotten) and the knowlege on this forum is incredible. Here is a picture of the carnage:
The rest of the gears look in good shape. It is in a new to me 73 that apparently used to be drag raced with slicks. Its got richmond 3.73 gears, th350 and a 454, maybe around 400hp. Will be driven 90%street with a few test and tune days at the track with street tires. I would prefer doing the work myself but my mechanical skills are limited to google, youtube and learning stuff on here so I don't think I want to try to mess with setting backlash and the paint stuff(yet). I would just take it to a shop if I had to do that. Also I have a moderate budget but nothing crazy.
So based on that what is the best solution in your guys' opinion? Get the oem posi repaired professionally? Or is it possible to change just 1 spider gear without removing the whole unit? But then why did it break to begin with... or buy an open carrier and put a lunchbox locker in it? or bite the bullet and buy a full locker? Or close it back up and forget I saw anything
Any suggestions would be appreciated, thanks gents!
