alternator brackets?

[thebeast61]

I am converting my 61 GMC with the 305 to an alternator. Does anyone know which brackets to get for this. I can find lots of different brackets but just not sure which ones work for my motor. I am going with the 12 SI delco if that matters.
I am trying to get the wiring harness from Mad electrical but he is hard to get a hold of and he dosent have online ordering.
Is there anything else that I will need?
Oh and what belt will i need or will the old one work?
Thank you

I am not sure about the belt or wiring but I know those alternator brackets are rather difficult to find. You can ask on Jolly's site if anyone is selling them there.

There is a universal mounting kit available. You can usually modify the gen. brackets to work.

Some options:
If you're keeping the stock exhaust with the generator adjustment mounting tabs on it, here's an option (these are somewhat "universal" so might be what you need with the ol GMC: http://www.alternatorparts.com/Alter...brackets_1.htm

Here's a whole slew of options, but you've probably already seen these online:

I've found that the adjustment arm is readily found at about any swap meet, but then again, I've been spoiled by Carlisle and Pomona...

Having said all that - sorry, but i'm not familiar with how the curved adjusting arm would/should mount to a GMC motor - may be able to improvise with one of these things though. Even chev had horizontally and vertically mounted bolts for adjusting arms, so something should work.

ok thanks for the info. i will give the universal a try.

Had to bring this thread back to the top. Can someone post pics of the generator and alternator brackets. Is there a big difference between the two? I'm looking to go with an alternator.
