I don't know whether the L175 regulator fits or not. I know that the alternator has a different connector. Mind didn't charge when I got it. The regulator was fried. The alternator worked, but the bearings were going out, so I got a new regulator and had the alternator rebuilt. If I were going to do it again, I'd convert it to a single wire alternator. In addition to making a simpler system, it would have gone from 15 to 40 amps.
