yes there was a place called plydo i think in teen. the guy that ran it passed away a few years ago. i heard his kids were now running it. they had a complete kit to do it. i bought one and it worked great.
HAMBer Olddaddy (Charlie) sells a kit that uses Mopar discs & GM calipers. He knows his stuff, too. Nice guy. I think it's also possible to use Ford Explorer brakes Key to both is a heavy plate bracket that bolts to existing spindle & mounts the brakes. Check out p-15/d-24 forum too.
I've had the Plydo disc kit on the stock axle of my '36 Dodge for 15 years now, still stopping great!
