1970 Duster Alternator Pulley Alignment

Thank you to everyone. To summarize, if I want to clean up this swap properly, I need to get a single pulley alternator, proper year water pump, and proper alternator mounting brackets. Do you know if I also need to swap the crankshaft pulley? I will likely want to replace the fan clutch while I'm in there.


Your water pump is fine, that's the correct one for 70 and later...


You need the triangluar alternator mounting bracket and single groove alternator pulley (Here's some links below) :
