<p>Glad it's resolved. I was drawn to the 16AC because I figured a
lesser output unit might be physically smaller. <br>
</p>
<p> I have a '69 with a 5-wire alternator which has an internal
regulator. Perhaps different accessories for the U. S. market.
(?) It's a rebuilt unit from Autozone, marketed under the
Duralast brand name, came with a lifetime warranty. Last
replacement was a number of years ago. Not even sure they carry
it now. Don't drive the B much now; it's main enemy is the
passage of time.</p>

doubt anyone would bother fitting one of those these days.
16/17/18ACR (internal regulation) should all be plug
compatible with each other but require a different plug if
replacing a 16AC. The original 16AC and ACR were 34 amps,
rising though the 17 to the 18 at 45 amps. If that 16AC
really is 45 amps then it's not a standard unit and may have
the same problem.</font></div>

<p>You didn't say what year the B is. I looked the alternator
up. I note there's a16AC unit,45A, for 68-69. Might be a
better fit. What unit came off the car?</p>
