Power steering pump?

[outlaw17]

Does the power steering pump on a small block have different mounts if it's a long or a short water pump? My plan was to use the original long water pump in the 68 I'm doing but the A/C comp and alternator brkt are both for short water pumps, I ordered for long but ended up with short, so I'm thinking the easiest thing may be to just go with a short pump, only problem I'm having is that I'm not sure how the P/S pump will line up. I ordered a Vintage air Gen IV system with a pass side compressor mount so the hoses would be nice and short and direct but this is biting me in the ass. Anything you guys can help me with would be great.
