QUICK PULL TIP: Using a 3/8 breaker bar vs a 3/8 ratchet to pull and release the tension of the belt tensioner to remove belt will allow for better leverage.

2. Remove the 2 bolts on the front of the alternator using a 15mm socket.

I've been in some yards that have not removed the batteries from the vehicles. Always check for batteries and make sure the negative is pulled first if one should come across a donor that still has a battery in it before tackling electrical parts removal.

Did anybody out there have some good websites to get some G body parts like fenders and headlight assemblies

J. Hunto's Garage says:

"Remanufactured" probably means it didn't work when it was installed. Owner probably got fed up called a tow truck, which just had a "New" alternator installed. 😉 Good job, thanks for sharing!

Mr. Scientifical says:

I use to have a 1987 luxury sport with that 4.3 fuel injection. Quick question
Would that NEWER truck have same engine and throttle body or will it be different?
