I'm not by any means trying to be $hity but from experience you would be better off buying a new ring and pinion set. I have been setting up ring and pinion gears for 20+ years and you will never get them right and to NOT make noise after they have set a wear pattern in another axle assembly but if you are ok with howling gears that's something you will have to deal with.

 

You can get away with using a used gear set with less than 500-800 miles on them to break-in a new wear pattern. A new set is around $200 bucks and get rid off the G80 and go with a Detroit Torsen unit. JMO of course!

between the two Motive is a pretty good set. Be sure you break them in properly with light acceleration and coasting, 20-30 min drives and allow full cool down.

Ok go to ECG East Coast Gear they have your pinion set 3.73 and up. Do yourself a favor don't use motive gear set people that used complain of whining noise

If not set up properly as per manufacture specs they will all whine. Be sure to follow their set up procedures. I have seen ALL manufactures gears whine when not set up properly and without a nice break-in period. If your guy uses an impact on diff repairs please find someone else to set your gears up.
