confused on alternator bracket mount

When I got my Jeep, it had a home made bracket to hold the alternator on. The bracket was a piece of junk, the alternator wobbled, and certainly wasn't mounted in the correct position. I got the correct brackets, and I have somewhat of an idea where it should go, but I have a couple of questions:

What bolt does the bottom bracket mount to? Is it on the oil pump housing like I have pictured?

The top mount straddles the heater hose outlet, do I need special spacers on the water pump bolts or special bolts to mount the bracket?

Thanks to all who reply...

water pump spacers for my upper alternator bracket

I'll just add on here to my thread... I made some 3/4" spacers for the upper alternator bracket, but my alternator seems to me not in line about a 1/2" behind the fan pulley and crank pulley. I still have to get the large spacer that goes in between the upper alt bracket and the head. Also the large 6"+ bolt that screws into the head.

I am not sure what size the water pump spacers are, and if I need to get longer ones. Any of you that can post pictures of your alternators mounted up in the stock arrangement, that would be much appreciated...

The top alternator bracket on my 1976 CJ-7 304 mounts directly to the water pump without any additional spacers. My water pump has the spacers built into the water pump housing, maybe you have the wrong water pump. My water pump is different than yours where the top alternator bracket mounts.

I am assuming this is a stock AMC 304.

Some replacement pumps come this way they give you spacers to stick in there.

My alternator pulley is about a 1/2 off as well, I may try to use some washers to space it out some.

BJF - Do you have the large bolt that goes into the head on the top mount? I got the right spacer tube for it. I have learned that there were two lengths that were used by AMC. Yes, my 304 is a stock '77 engine. I posted two more pictures that show the alternator alignment. I just screwed in a temporary threaded rod into the head so I can check the alignment of the pulleys. It looks a little off... not sure what to do to bring it forward without adding more shims to everything. I just wish someone would post their pics of their stock 304 setup, because I cannot find any pictures elsewhere, even in the service manual...

Here you go. It looks like you almost have it just need the back spacer.

Skidplate:

Here is a picture of the spacer underpar showed installed on my 1976 CJ-7 alternator, the spacer measures 2 11/16 inches long. Hopefully this is what you are looking for.

Yes I have the bolt that goes into the head, I also have the above spacer and a 2nd small spacer about 3/4 of and inch in length they kinda stack in line to make it easier to remove them.

I'll get some pics when I get home this weekend.

I just got a new water pump from Advance auto for my stock CJ7 304. It did not have spacers with it for the from Alt. bracket. The old one had it built in. Should the new one have spacers? Can I buy them? Does anyone know if there is a brand out there that has them built in like the old one I took off?

i am having similar problems, was in the process of a weekend rebuild/seal. put everything back together and i cannot for the life of me figure out how to arrange my brackets to support my alternator . im always left with a extra ^6" bolt with a slight 'Z' bend to it. plus.
so i know the bolt goes in some where close, and obviously 'Z bars to the alt bolt as additional support.,
but i have no photos to go off of. i cannot tell if i have used the wrong bolt somewhere else by accident.
if anyone has any pictures of a
1986 amc 360 detailed alternator bracket photos it woul be much appreciated
go jeep.
