Try one of the top 4 on this list, as far as I can tell they are a direct bolt on...

We bought this one, ^ it has worked perfectly for a whole 75 miles or so,
charges 13.9 V at idle with undersized pulleys, and 14.1 V at speed.

It will be a direct bolt on with the possible exception of the alternator
spacer, I don't know for sure because I had to start mostly from scratch
with my mounting.

 

I bought SUM-810302 and a couple things that I had issues with when installing were; the charging stud was resting on the block when mounted with the stock lower bracket and belt. So I extended the lower bracket 1.5 inches on the non slotted side with a slight upward angle to clear the bigger Alternator fan, then I added a belt that was an inch longer. After that I cut the extra length off of the charging stud. Now I have plenty of block clearance and room for belt adjustment.
