1990s Chevy 3500HD trucks came with a 700R4 from the factory, with a big drum parking brake on the back of it. Maybe you could find one of those in a wrecking yard and pull that setup. Since there was a factory option, it might not be too difficult.. (yeah right-famous last words)!!
Just a note that from what I know, 1990s Chevy 3500HD trucks came with heavy duty RPO MT1 4LE80 transmissions with the rear mounted parking brake drum setup. Two wheel drive from the factory, but there were some after market companies that converted some trucks to 4WD. I couldn't find anything noting there was a parking brake equipped 700R4, but I've been wrong before - lol.
