I have wanted to do the same. The mud-dragger location of the alternator at the bottom of the belt drives is made worse when the splash guard is removed (on purpose or by trail obstacles.) Feeding the alternator a steady diet of mud will exercise the lifetime warranty you thoughtfully bought replacing the last one.
The '96 up seem to have cured the problem - the alternator is topside where the '90 has the A/C compressor - which is moved under the p/s pump. This looks like it requires a complete accy mount changeover, new a/c hoses, and a different alternator as the bolt up is different on the late model alt (not being a CS130.) This would seem to be the most efficient way to go because parts are readily available for the salvage yard, the serpentine belt remains stock (a '96 up) and everything bolts on - no trying to find non-exisiting applications from the V-8 hot rod industry.
If anyone knows of a interference issue because of HO vs non-HO, please speak up; most write ups concentrate on head/block issues, and don't mention any mount problems.
