I know at one point in this conversation you guys were talking about bearings. I found this on another site:

"I finally found some for the 3/4 ton and 1 ton trucks.
On Chevofthe40s.com
Part #909025R(outer)
#909026R(Inner)
I contacted customer service and they assured me that these were taper roller bearing replacements for the 3/4 ton and 1 ton trucks.

Take it for what its worth...Let me know if anyone has tried these bearings.
