68 GMC... Converted to p.s./p.b. using parts off other vehicles. Power steering pump and mounting hardware I got from a 70's six cylinder and bought one of the mounting brackets from the Chevy dealer about 6-7 years ago. They still had them for the newer 6's.
As you can see from the pics, I had to cut a piece of the mounting bracket since the hole didn't line up and it interfered with the alignment of the pump. There's enough other mounting hardware that it does not move...
