ol' goat brake conversion

Im helping my Dad put a conversion kit on his '66 from drums to rotors. Problem comes in where the power booster sits on the fire wall. It interferes with the wiper motor. They both wont fit. Ive looked and cant find a smaller wiper motor. Anyone know of a smaller motor for this type of situation?

 

There are a few ops,smaller booster or spacing out the booster to just miss the wippers snappers.
Some one may of done it?

 

We dont specialize in musclecars here.

 

I would think a GTO forum would be more help.

 

There are smaller boosters. or go without a booster.?

 

Get the smaller booster.
