Very cool. Like the brass NAPCO plaques, too.

Looks very similar to mine. Only difference is mine has a second driveshaft and parking brake drum where the PTO is on yours.

"Chatter" on the CCKW sites says to keep an eye on the transfer case to frame bolts, as they tend to loosen up and can cause the case to crack -although I have not personally experienced this on my truck.

The books and TMs always refer to these axles a "corporate" or being made by Chevrolet. Did Eaton make them for Chevy, or was this an Eaton design produced by them ?

Best Regards...
