Replacing your battery when the new alt goes in is a very good idea if it'* over a year old. The failing alternator may have stressed it too much.

Failures of alts are more common in the SC cars due to the extra heat and placement of the alternator closer to the firewall/rear manifold. The L27 and L36 are mounted more along the mid-point of the engine axis, higher up, and tend to heat soak less.

A 200 amp alternator will rob more hp than a 160, 125, or 105.

AC Delco Remans are the best choice for a 105, with Napa'* warrantied units a close second (from the experiences I've seen here).

Just a few more data points here:

1) Trak Auto (if they're still in business in your area)
2) Lee Automotive (midwest/Illinois)

Ones to avoid, based on personal inspection, as no-name rebuilds, not AC-Delco like above:

1) AutoZone
2) Farm & Fleet

Given that Bonnes like to eat their alternators, warranty coverage is something to consider when looking for a replacement.

I bought my car in 95 with 10K miles on it, and replaced the battery about 3 to 4 years ago. My alternator is still running strong. Based on my experience, you don't necessarily need to replace them as a pair. Maybe I'm just lucky.

Yeah, Ive never agreed with the Battery + Alternator replacement theory. I get the battery checked and tested when the alt goes, but if it tests fine, it stays. Usually I replace alternators because the bearings go, not because the voltage drops.

Does anybody know if the alternator bearings can be replaced, or does the whole atlernator need to be changed out?

Usually by the time the bearings are known to be bad, they've damaged the shaft, as well. Rebuilding an alternator yourself isn't an easy task, either. Having it rebuilt at a local business is an option, though.
