Is this an alternator bracket and where does it go?

So I got just the engine (no car) 302 from 1975 I recon with an automatic transmission. With it came this loose bracket part number D5ZE-10A336-AC if I Google the number it says it's an alternator bracket but I got no alternator for it yet and I am just wondering where it goes. I think it's on the passenger side somewhere but I don't know where.

Could someone post a picture or a diagram of how and where it goes please?

First Attempt

I am embarrassed to admit what a circus mounting the alternator to this motor it has turned out to be, I feel like I'm constantly trying to fit a square peg in a round hole. No wonder the motor came with no alternator and a single orphaned bracket.

So here's how the First Attempt went down. After parusing eBay (first picture) I discovered that for some post 70s Mustangs it takes three to Tango, three brackets that is. I already had one of them so I set out to get the other two. A "true" 36 year old Cougar [wink wink] with a 351 gave up what I needed.

So I was armed with:

Rear Bracket: D5ZE-10A336-AC

Upper Bracket: D00E-10156-A

Lower Bracket: D3AE-101 5-CA

Giving me plenty of rythm and floor space, but they just wouldn't dance together, the long pivot bolt holes did not align, and even if they did the heater hoses would interfere with the alternator body.

... back to the drawing board...

Thank you for your help COBRAIIW especially the picture, it helped a lot, I think I finally realized that my bracket is slightly different from the one on your picture and mine would not mount horizontally like that, mine mounts vertically like this:

Second Attempt

Though the second attempt failed, here it is documented for prosperity. Basically I went out and bought a Scott Drake alternator bracket set for the first generation Mustangs for $20 bucks. These are the dime a dozen brackets you see in any catalog, usually in black or chrome. In this attempt only the two brackets you see were used, the third rusty triangular one sat this one out.

PROBLEM:

Well the long alternator pivot bolt did align with the outside hole on the cylinder head but the top bracket was preventing me from mounting the water pump pulley. It wouldn't just rub, the pulley would not go on all the way at all.

You can see the difference in the brackets below:

Third Attempt

What, third attempt who does this guy think he is Thomas Edison? Doesn't he read prior posts, others have shown him how to mount this darn thing.

OK, this third attempt was successful. Yes others have shown me how to do it, but my actions and some of these posts are not in chronological order. I choose to document this so that others don't repeat the same mistakes I do, or they can, lol?

The problem was that my triangular rusty bracket/spacer which I started this post with is a bit different than what I needed in order to mate with the brackets I pulled off of that 76 Cougar 351 (see First Attempt above).

So I went out and found the correct rear triangular bracket/spacer its the silver one in the pictures, at a swamp meet half a mile away from my house for $5.00 bucks. Needless to say I was tickled pink when I brought it home and all the holes aligned, the Mustang Gods were smiling that day, that's for sure.

So the correct combination is:

Rear Bracket: D10E-10A336-AA
Upper Bracket: D00E-10156-A
Lower Bracket: D3AE-101 5-CA

That is a 1970-73 type setup, maybe not concourse correct, lol, but it will work, I am being told that my orignial bracket can work if I find the matching other two... stay tunned for Fourth Attempt (oh God!)
