Slant to 318 Swap My Parts List / Whats missing?
If your car has power steering, you will need to get the ps pump from a 64-69 model car. The brackets for the ps pump mount off the water pump for the early a's.
The mounting brackets are different from slant 6 p/s pump to the v-8 p/s pump...
The 70 and later power steering pump/brackets mount off the timing chain cover holes.
