Need help with P/S install

So here is a website I found with pictures of the 3 pumps:

Chrysler/ Federal
Early Saginaw
Late Saginaw

So what I have is 2 of the late Saginaws and 1 Chrysler/ Federal. The 2 Saginaw pumps both have different brackets and the Chrysler/ Federal has a HUGE pulley and a bracket different than posted by you guys. Several questions come to mind:
1. Which is better?
2. Which leaves more room for access with my A/C set up?
3. Can modifications be made to the Chrysler/ Federal to improve road feedback and reduce the power assist like you can with the Saginaw?

Pic of my A/C set up coming asap.
