Brake pedal assembly

[Dyno68FB]

I was hoping to borrow some of the extensive knowledge that's in this forum. As a newbie I made a classic mistake months ago. I bought a new pedal assembly on craigslist that allegedly came out of a 67 Mustang. I have a 68 C4 car that I'm doing a T5 conversion on. I referbed the pedal assembly replace the bearings and put it back in the car. As I'm going to replace my Midland style brake booster I realized it will not fit in the newly acquired pedal Assembly. On the assembly there are four welded nuts instead of the one that was on my original. Obviously the booster has threaded bolts that are supposed to pass through the firewall. This cannot be done due to the nuts that are welded on the brake pedal assembly. I would simply drill out the thread pattern on these nuts but the bolts on the booster or not long enough. Knowing what I just described can anyone tell me where this brake pedal assembly with the four welded nuts on it in a Midland style pattern came from?

Sounds like a 65/66 pedal assembly except that the nuts are not "welded" but rather captured. see pics

The non power brake pedal support for the 67-68 have the 4 crimped nuts like the 65-66 pictured above. When I converted mine to power disk brakes from manual drums, I simply drilled out these nuts so the power booster bolts would go through them. You also have to use the upper pivot for the power brake pedal to get the angles correct for the plunger rod.

something else to consider is that a 67 pedal may rub on the 68 column. The 68 column is a bigger diameter than the spear-O-matic in the 67. I beleive the 68 pedal has a different bend to clear the bigger column....

This is a good example of pedal differences and Craig is right, the '68+ have a greater bend to go around the larger collapseable column of 68+. I had to swap my '67 pedal out when I installed the collapsing column.

oh well the writing didn't carry over you'll have to look at the link.

Thanks for all the help. So I ordered a Referb midland style booster and cut off the nuts on my pedal assembly. Apparently the brake pedal assembly I picked up on CL was for a 67 man trans with man brakes. I ordered a new brake pedal from CJ Pony. I am wondering if I did not have to do that and if my original brake pedal from my auto trans with power brake would work if I trim the stomp pad for the pedal. The better question is if it would look right. I know it will work. The pictures of the CJ pedal shows it doesn't bend as far to the passenger side as my original pedal does. I see the comments about the sterring column, but my manual brake/trans pedal has the same bend as the CJ pedal and the fits in my 68. However I have tried neither with a gas pedal in the car.
