I assume you have power steering so the bracket needs to be moved to the pass side, down low. One way to go is the Ranger alt bracket. It's only a certain year that works and I'm not sure what year that is. I do know they're very hard too find and expensive when you do. You also need a specific alt for that bracket and the whole thing is kinda ugly, if you ask me!
I ran into the same dilema with my rotated upper. What I did was use an '89 Mustang upper A/C bracket. Spaced it out 1-1/2". Fabbed a supporting arm out of 1/4" bar stock and fabbed a lower bracket out of 3/16" bar stock. I'm running it off a double crank pulley. Pretty easy fab job.
