Got a 8 3/4 rear-end with 4.10 gears. The code is: 2881489, translated as a 489-Case, built between 69-74.
1st) The few sites I've looked at all say there should be a big "9" stamped on the left side. This one has a "Y" on the left, not 9. What does that mean? Just curious, before I order gears.
2nd) How about brands: Yukon (from Randy's or ?), Motive, Strange, Richmond (Summit), & USA Standard (Randy's & eBay). Range from $200 for most to $400 for Yukon. Seems most people are happy with any of these? Going to a 3.55. Do I need to order the complete install kit with all the small components, or just the ring & pinion set? The diffy is already rebuilt with very few miles. A shop is doing the swap for me.
3rd) How do you feel about a 4WheelParts type shop? The svc. mgr. says they've done a TON of rear-end gear swaps for trucks incl. Mopar and would be very comfortable doing this. But I know some people will think this might not be the best idea. Thoughts?
It's a 440, 727-auto w/ Hughes 3500 converter. I'd like it to drive nicely on the highway without winding out like a Singer sewing machine like it does now, lol. Not much drag-racing except maybe Mopar wknd or club days at Bandimere.
