My friend with a 72 3/4T had a heck of the time finding a replacement 3/4T booster when his failed. I am mentioning this as it is likely you could change from the 3/4T to the 1/2T and possible break even or even make a few $.
Good point - if I just sell this one and find a 1/2 ton I'm in the same spot. I had read the below link that made it seem feasible, but I don't really want to start a science project and have it be a pain to find replacement parts in the future.

I believe you can actually get the rod on, but the brake pedal is on the floor by the time it's all said and done. No worky.
Thanks - I hadn't thought about the geometry on the back of the booster to the pedal, I'll measure to confirm but that is yet another reason to go with designated c10 parts..
