Well I’ve got a little bit more to add. Here’s a couple pictures, I thought I had a better angle of it all but this is the best I have one my phone. New master cylinder, hydraboost lines are all done. All that’s left in the brake system is to rebuild the rear brakes and bend up a hard line for the rear axle. Getting closer. I haven’t had much to time to work on it this summer, I’ve had family visiting from home off and on most of the summer. Hopefully in the next few weeks I can get back to it. Really in order to running and driving I probably have a months’ worth of work but it’s finding that month to work on it that can be hard. Here’s an awkward picture of the hydraboost setup. I’ll get a better one soon. I’ll also outline how I went about the hydraboost swap in case anyone is curious.

For my hydraboost I used the following:
Captainfab hydraboost mount plate
hydraboost unit from an 08 Silverado 2500hd, from the stock 72 pump to the h.b. Unit I used a combination of a new line for a 77 k30 with h.b. And the line from the 08. I cut the booster side of the k30 line and flared it so I could use a union and adapt it to the o ring metric side of the 08 line as seen below(note the union in the line coming from the h.b.). For the booster to the pump I used the line from the 08. I cut the metric nut off of the steering box side and used the standard nut and re flared it. For the return I used the factory hard line on the steering box and the 08 factory molded rubber. I joined the two return lines from the booster and box with a brass hose tee into the single return on the 72 pump. I also used the stock NAPA replacement master cylinder for a 72 K20 and the original proportioning valve. I’ll get some better pictures soon. I found another one with the booster to box line mocked up I’ll post it up too. It will require very slight trimming of the inner fender to clear the steering box side of the line.
