Big block bracket questions - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hi, I'm sorting the brackets for my big block swap next month and have a few questions. The engine I bought was supposed to have all the brackets for the PS and Alt, but some seem to be missing? From the pics, does anyone know what is missing from each? I just have them bolted to a core in my garage to fit them for now.
For the Alt, I know it's missing the rod that goes from the top bracket to the manifold?
The PS, there's only 1 bracket, seems there should be one for adjustment as well?
Also, where does the reservoir fasten?

Thanks for the reply

Looks like your missing the back 3/8 rod for alt bracket setup and the small lower adjusting bracket for PS pump. The reservoir mounts on fender over by the washer jug

Cool, thanks for the quick reply

Is there a bracket that bolts to the fender first for the reservoir, or screwed in from the inside of the fender?
Thanks

Screwed in from the inside

Searching the forum a bit, I noticed there are 2 types of top brackets for the Alt, a cleaner looking style that has a mount 2 point mount to the intake and head, and the type like I have. Will the other type top bracket work with what I have? Mine is also from an AC truck.
If so, does anyone have one available?
Thanks

The upper alt mount you have is 72 only
