A bodies never had 11" drum brakes, Period. They had 9" and 10" drums and Kelsey-Hayes discs up until 1972. From '73-'76 they had the same drum choices but the discs were 10.87" slider caliper units. Here's my thinking. We have a frustrated member who may or may not give up the hobby based on answers he may or may not get here. He already knows that he has 9" drums on his car and needs 10" drum spindles to use the disc brake kit he has chosen, so he gets a lot more credit in my eyes than a dipstick ebag seller that obviously doesn't know what he is selling and only cares about the money. I'm sorry that my attempt to provide an answer caused your panties to get in a wad because I did not observe the proprieties and stand by and wring my hands and gnash my teeth and ask more questions until a frustrated member abandoned all hope because every time he asked something, more information was needed so the gurus could pick one from column A and emerge with their reputations untarnished. I have a simple rule of thumb when it comes to questions. Answer it or say "I don't know" and stay out of it. You may want to consider doing likewise Oklacarcollecto because your sniping is starting to really get on my nerves...
