Just peeked under the UPS truck today. rockwell 2.5 ton with 13 inch disks and dual piston calipers...looks about 59 inchs from the backing plates.

You wanna race the truck, don't ya? <IMG SRC="smilies/bounce.gif" border="0">

Rockwells are pretty easy to find. I hadd a list at work of most of the apps for the axle.

I'll see if I can find it.

my bell housing is from a UPS truck...Hyd clutch...pass side..

I would be extremely interested in the list of what all rockwells came in as well as gear ratios and widths if possible.....front and rear if possible.

I know two different guys running Dana 70's that came from the rear of smaller UPS "Package Cars". One, even dug a 70 out of the dumpster (with the help of 2 other guys) behind the UPS terminal & hauled it home in the trunk of his Caprice :eek:

The NV4500 I have came from a Fed Ex truck.

Let me see if I can find it...My work does CV joints. And Rockwells use CV joints. That is why I have the list, in case you were wondering.
