The power brake booster is from a 1987 2.3L Mustang. With the 1965-66 Mustang only weighing 2,700
- 2,800 pounds this booster works great. It comes with a long rod for the master cylinder so be sure to get the correct master
cylinder. More on that later.
The stud pattern for the booster is not too much of a problem. As detailed on the previously mentioned
webpage you will have to open up two holes and drill two holes. This is not very difficult. It just takes some time and care.
Make a pattern of the studs on a piece of manilla folder. This is sturdier than paper and works fine.
Note that in the picture below the pattern is bolted in place BACKWARDS. Yes, he did notice this before he drilled holes.
