Unless you are doing an OEM type car it just seems there are glitches at every turn eh? I just got home with my new power booster, it is from a 2.3 liter '92 Mustang. I purchased it for my ATand 4 wheel disc equipped 67 project. Based almost completely on the advice from this thread:

Anyhow, it is anything but a bolt-in. The problem is the four studs that go through the firewall and into the passenger compartment are not in the right pattern. To be honest, I was pretty suprised that in all the years FoMoCo kept the same bolt pattern. Anyhow, the old booster had four bolts that were not equally spaced and the Fox booster has all four bolts arranged in an almost perfect square, slight off so you don't accidentally fit in sideways or upside down I guess (as if the vacuum port position wasn't clear enough). I've got two new holes to drill in the firewall, got em going but will have to go buy a larger drill bit to finish.
It gets worse too. The Wilwood MC uses and abosutely HUGE rear port. I was unable to find one large enough in all the local parts stores and even online had trouble. Wilwood themselves don't sell one (that really sucks since it is their parts...grrrrr). Found one via telephone from California (Orme Brothers), the fitting was only $1.75 but I piad $7 for 1st class USPS mail. Got a brake line, cut the old standard fitting off, took it to Brake Check to have them re-flare the line and got over THAT hurdle. Then I find that the Wilwood MC does not fit the 1992 booster, the two studs line up but the non-removeable pushrod is WAAAAY too long, so I'll need a spacer or "something" to get that going.
...and I wonder why this car is taking a few years worth of Saturdays....sigh.
I'm stopping for now and getting a beer (or 10).
