My alternator just went flat on my 96 f350 with a 5.8L.
Any common upgrades with donor parts to upgrade like a 3G or whatever. Stock replacement is a 95 amp. Just looking for any ideas,tips

 

Yes, the 95A is already a 3G, albeit a small case one, so you already have the proper harness to install a bigger alternator. You can search for a large case 3G of the same configuration as yours and you'll have an 130-160A output. The large case is easy to tell apart because there are three radial rows of 2 holes in the front face of the case, just behind the pulley (yours has 4 holes in the same arrangement). Fixing your current alternator probably is a $10 ordeal (brush replacement, maybe a regulator replacement) and a good measure to keep a spare at hand.

 

Is it bolt on if I pull one from like a f450 or ambulance or something with the larger case

 

You'll likely need to grind the mounting bracket to clear the larger (148mm) body of the 130A alternator.

There are pictures on the RJM/oldfuelinjection website.

(Edit)
I see you have a '96 side mount alternator.
Sorry to add confusion.
