Bosch Alternator questions Options

[TRP]

Hello Gang!

While the motor is out being rebuilt I figured I would look at the starter and alternator and replace what might need replacing. The starter has a cracked cap on the solenoid, so I've ordered a new starter, will be here Monday. I'll ship the core back and recoup some of that money.

The alternator (Al75x) makes a funny noise when I spin it. It appears to be older possibly the original to the motor (82k miles), so I think I'm going to replace it while it's out. I ordered one from Pelican, they called to let me know that the one they had is sold and they didn't know when they would get more. Sierra Madre is out as well. Is this something I can just get from my FLAPS? I understand that it's doubtful that they will have on on the shelf, but is there any issue with going Oriley or Autozone? A Bosch Al75x should be universal, no?

Any benefit/risk with going with the 70amp unit?

Where is the voltage regulator on a 1975? is that hiding over on the relay board?

Thanks!
Ted

I believe X in the part number denotes and exchange unit ,would suspect the original was most likely exchanged as a core for replacement ,the early exchange units were pretty good but newer on don't appear to be that great ,I have done my share of Bosch rebuilds on altenators ,the 55amp units are are a DIY job if only doing brushes and bearing ,when you need diode work in gets put done to a suitable shop .
I believe the 75 amp unit fits with a change to vanagon unit which has and external cooling fan .
Good luck.
