I recently aquired a 1979 GMC 7000 4x4 with a 427 and Allison trans. It has the American -Coleman 4x4 conversion. I was wondering if anyone has any info or insight to provide on the American -Coleman conversion and parts for the front axle.

I know the the transfer case is a Rockwell, but did American coleman manufacture make the front axle or is it some variation of a Rockwell axle?

Thanks,
Jeff
