i have a 4th gen rear out of a 97 formula... its 4 channel but doesnt have any backing plates or sensors on it... its got moser hardened replacement axels completely rebuilt with new GM performance gears complete new bearing kit and new axel bearings also... its 3.42 ratio but also have 4.10 gears that were installed for a short period of time for it... its got an auburn posi unit also...its got a very minor leak at the pinion seal pretty common for 10 bolts from what iv seen.... its got a slight whine to it.. but the gear wear pattern looks good and the backlash seems about right just checking it by hand (i didnt set the gears my self)... on this set up it only has about 4 track passes on it since rebuild and probably only has about 2500-3000 miles on the rebuild... ill take $300 obo could use a few coats of paint and a good cleaning to make it look perfect... it was removed to install a 12 bolt on my new setup...
