Hy K9sicem, I can't find all the info I would like to have to confirm or deny what I'm going to say, the wheel cylinders do not have the same part numbers, or the same bore sizes. I think but I'm not positive that Chev switched from "huck" to "bendix" brakes in 51 across the marque. You may be able to install your cylinders and shoes to the backing plates, as both appear to be 11" brakes. However I would strongly recomend you rebuild the Bendix brakes and use them, as they are a much more efficient brake. You could always post your fresh wheel cylinders and parts in the for sale area to recoup some of your investment in them, hope that helps.
