New pair of Alum ap Lockheed calipers,#CP2195-1-2, a left and a right. 2 lb 6 oz including pads(less than 1/2 of the cast iron weight). They probably fit the earlier 9.5 in discs(too small for my 9.85/9.75 in discs), but do have the right bolt spacing and offset. The pistons appear to be LD 19 size. Including pads, price is $300 plus shipping for the pair.
