8 1/4 Rear Installed, now about that Carrier...

I'd take a hike over to NAPA's web site and do some research on carrier bearings for 8 1/4 axles, maybe they sent you a set for the later style 8 1/4 used in dakotas ??? Did you save your old bearings ? Are they on the old carrier ? Maybe you can compare them that way. As you may also know there are identification numbers on all bearings so all you need to do is find which were originally on your open carrier and compare. I am not an expert on these things, so check carefully.
