Thanks for all the info guys! I was going to try to mount a mid-80's S-10 MC/booster on my '67, but those mount flush to the firewall, like I was wanting. However it interferes with the automatic shift lever (that the linkage hooks to). I really hate how bulky and cluttered the stock setup looks, so I think I'll just go with the master cylinder alone. Again, its' not a daily driver, so it shouldn't be a big deal.
