I don't think so, the difference is in in the carrier. I ordered the Precision Gears C83:410 gears. C83 seems to be the designator for the Chrysler 8 1/4 (which is actually 8 3/8) Its also the first part of the part number for the master rebuild kit from precision, C83MOKIT.
I got mine from
http://www.reiderracing.com/, primarily because they were able to get the Dana/Spicer gears for the front. The rear gears are made by a couple of companys but Precision is a pretty good name.
Take this all with a grain of salt, since I haven't had mine installed yet and these could be completely wrong
