Go to your local auto parts store and get the cheapest Delco internal regulated alternator you can get for an early 80's GM product. 9 o'clock orientation on the edge plug for the front mount distributor (goes on right side), 3 o'clock orientation for the side mount distributor (goes on left side). That way the plug goes toward the engine and won't get bumped or broken as easily.
You can change orientation if you are careful. Any one of the amp ratings will work
