The 64 I have just started building for my son is not equipped with power brakes. What brake booster should I use and would a booster from a 72-73 Chevy half ton work? What other related parts would I need? I am in the very early stages of this build so I am hungry for knowledge. I am sure some of y'all can help me from what I have read on other pages. Thanks.

I'm using a booster from a '79 Big Ten. Your 72-73 should work fine. May not be a direct bolt-on, but shouldn't require any major mods.

Your 79 booster was a direct bolt on?

I converted to a two-chamber master and boosted brakes, but kept the front drums. I'm FAR from an expert, but I don't think it's a good idea to use a master for drums that is intended for disc application. Also, the stock pedal ratio has too much leverage when used with a power booster. On my truck, I was able to use the stock ratio pedal and firewall hole because I lowered the push ratio under the hood using a small bellcrank that I got from a mid-seventies International Scout. I used the Scout's small-diamenter booster and found that a two-chamber DRUM BRAKE master cylinder for a 68 chevy pickup bolts to it. I made the firewall setup for the bellcrank and booster mount in a way that offsets the booster and master towards the left. (by turning the bellcrank sideways) The cool thing about this was that I didn't hafta drill any new holes in the truck, so, even though there was a bit of fab involved, it was bolt-on after that!  What you are seeing here is a piece of 1/4" aluminum plate with the plunger hole drilled out and holes drilled in it to co-incide with existing bolt holes that are threaded on the inside of the cab into the column/pedal mounts and existing master bolt holes. Where the bolt heads would interfere with the booster/bellcrank mounts or other items, the holes were either countersunk and fitted with flat-head allen bolts or continued thru the next piece for thru-bolting. The top and bottom bellcrank/booster mount are made out of 4" flat-flange aluminum channel (flanges turned away from each other) and are bolted to the 1/4" plate with flathead allen bolts countersunk from the back side so that the plate would lay flat against the firewall |

Is there an easier way of doing this modification???
I am doing the same thing on my truck.
Can't you just use a master cylinder/booster off a 70-73 truck?

I don't believe that a disc brake master will work properly with drum brakes. Pedal ratio is also different for boosted brakes, but I suppose you could step lightly on the pedal (?)
I had to imagineer this setup and build it from a mental picture, but it wasn't rocket science and I used common tools that most guys own. I'm not a machinist or particularly well equipped. I used some Scout pieces because I had an opportunity to strip whatever I might be able to use off of a Scout that a friend was dismantling. Moving the booster/MC assy to the left facilitated a better pedal ratio and also made space for the A/C compressor to reside in it's stock mid-seventies location on the engine while allowing fat/tall aluminum valve covers.
I'm not saying that the way I did this is the best or only way..... I'm just offering something that works as a possibility to be copied

Dirty Donny:
If I had the money, I would buy it off of you right now.
I met you guys out at the Show 'N' Shine and the All Truck Nats this year. Nice trucks ya got. One of these days I would like to check all of them out.
Meanwhile I am working on my 66 Burb. Trying to figure stuff out, like the brake booster. Right now I am working on the seating. I am going with a whole new system for seating - more modern. Also still fidling with the sliding glass. Oh what fun!
See ya around.
