This is a sportsman pak-mule, not a pack-mule made by drivex.
These were manufactured by Christiansen Machine. They had a machine shop in Ranchita back in the days. In my Grandpas days our families used to go camping and duning together.
We fired up an old pak a few days ago that we picked up from thier shop a while back. Had to modify a few parts but is works!
You said you had a manual and receipt? Is there any way you could scan those and email them to me?

According to my dad, the Christiansans sued tote-gote for copyright but since they never filed for the patents on the pak they didn't win the lawsuit. Tote then took off when it being mass produced. The paks just died out. I guess my Gpa owned 5-6 at one point.
I know they still own the ranch in ranchita but the machine business is long gone. Most of the family members my dad remembers have passed. It might be worth while calling the business line and seeing if anyone picks up. They might have some spare parts lying around.
I don't know what the heck the drivex pack-mule is. My dad doesn't know either.
