GM part search

[92whiteZ]

this is a resourceful group and better sleuths than i:

I have a baer big brake kit on my 92 c1500 pickup. the kit is made up of a modified stock spindle and a hub/wheel bearings separate from the rotor. in a stock part the rotor/hub/wheel bearings are all one unit.

baer discontinued the kit long ago. I need a new hub assembly. called them a few times to see what the hub part number or unit came from. no one could help; some said they didn't know and it was so long ago they don't have a part number, others just said it was no longer available.

the part looks like a stock piece for some car. only numbers I can find on it are "6040016" . that isn't a baer part number.

it's a 5x5 bolt patten, none of the caprice/full size Chevrolet cars appear to use a separate hub/rotor configuration.

anyone have suggestions as to how I can find out what this is from?

thx
