One more pic that has been floating around the hydroboost topic for quite sometime. I swapped hydroboost onto my '78 K10 a few years ago and love it. I personally feel it is a much more worthwhile swap over rear disks, at least on the heavier trucks with full-floating rear axles anyway.
I'm not sure who we owe credit to for taking this picture measurements...but thank you!
