I just finished converting my '69 Z/28 from manual to power steering, using all correct stock parts - the only problem I found is that the pump pulley lines up about 1/4" rearward of being perfectly aligned with the rear (closest to the engine) crank pulley groove, and the return hose in the kit was about 6" too short - had to have the auto parts store cut me a new one 6" longer. Looking at it from the front, I have about 1-1/4" clearance between the O.D. of the pump pulley and the O.D. of the crank pulley. The back of the pump is spaced about 3/8" from the front of the block.
Are you sure you have the correct pulleys for your setup? The '69 non-Z28 and non-A/C long water pump arrangement (pulley groove closest to the engine drives the P/S pump) uses a 3956666 crank pulley, 3932402 water pump pulley, and 3770509 P/S pump pulley; A/C changes the water pump pulley to 3932430, the crank pulley to 3932428, and the P/S pump pulley to 3941107.
My pump tower sits about 5 degrees inboard of vertical with the adjuster bottomed out at the top of the slot, and about 15 degrees inboard of vertical with the pump all the way up so the adjuster bolt is at the bottom of the slot.
