Summit carries superior. They are like 250. If you go Moser you get a ten year warranty, but they are 300 and custom. So you have to get all the measurements, then call them. If your rearend is stock, they will more than likely have them in stock at summit.Those have a 2 year warranty. I would recommend the new style axle retainers from moser. They slip on the axle AFTER it is installed. It looks like a C, so if you ever change axles again, you don't have to pay to have the bearings taken off. You won't have to pay to have the ones taken of your current axles either. They are around $20 and I think you may pay more than that to have the old ones taken off.
