I'm looking for a 12vlt starter and alternator that I could either use directly or use the parts to convert my 24vlt starter and alternator to 12vlt. I know 2lt stuff would work perfect, those are hard to find and expensive.

I have a 85 13bt. I've heard an 83 3b starter and alternator would do the trick. Thanks
