anybody ever seen/know anything about

this strange brand disc brake kit. i was told that you use it on an a body drum brake spindle. there were no instructions with it. i looked at strange's web site and it does not show this kit. (of course it doesn't). jfz calipers, which google says are also wilwoods. they are 4 piston calipers. the hubs have 4.5/4.75 inch bolt pattern. would like to know more info, if anyone has it. i got rid of my 10 inch a body spindles, so hard to visualize how it fits. hubs have dual bolt pattern and the studs are screw in from the back. tia. rick w.
