Nick, I've been through the nightmare of the front 11x3 lockheeds on my 73 1110 (2wd fa-1 axle). I had the shoes religned and still had problems. I finaly gave up after much frustration and sent my spindles to abs power brake in orange,CA. For about $500 they machine your spindle to accept a disc hub, fabricate a bracket for a disc caliper and provide a rebuilt set of calipers, hoses, and new discs they use early 80's GM passenger car stuff- cheap, effective and common. The only problem I ran into was the hose they provided didn't match uo on the frame end. I sent examples of the 2 hose ends and length specs to ej johnston auto in georgia where they made custom braided stainless steel hoses for about $45. Think about it, return springs are unavailable for the lockheed brakes. If one of yours breaks, good luck finding a replacement. I tried sourcing alternative springs, but because of the unique design of the brake (spring attaches to the inner side of the shoe itself), nothing comes close (even after my local napa let me rummage through all their brake springs). If you want a set of new drums and wheels cylinders, along with those return springs made of unobtainium, I've got them and would be glad to get rid of them to erase any memory of the many problems they caused.
