6 Lug Disc brake swap

[Hard Luck]

I just rebuilt my 69 Chev suspension drum brake with 2" notched lower a-arms and dropped spring all around.

Has anyone done a 6 lug disc brake conversion using factory parts. I see a lot of the later model 6 lug wheels around but can't seem to find out what truck years and models they came off of.

I just picked up a set of 71 disc spindles and am thinking about using adaptor bearings with the later rotors. I will use a reamer to make the disc spindles fit my drum ball joints.

Also want to use some 2 or 4 piston calipers, the stock 1 piston units seem a little less than perfect since they are the same ones used on a 6cyl Nova.

Any part of this puzzle helps. Thanks.
