that rear bracket is different than other rear brackets used on smaller alternators and it curves away from the alternator at the top.

The bracket above picture is for a NON 80 amp set up and that bracket will not line up to the Boss hole on the back of the 80 amp alternator
To illustrate, the picture below the bracket on left is the more common one for the 55 amp alt. The one on the right is for the fixed position 80 amp Alternator. Its like a mirror image of the other one.

Sorry for the short hijack...

I am confused..did 80 amp get a rear holding bracket or not...sorry about this

The 80 Amp alternator, which is the one that is mounted in a non-adjustable position (the idler pulley sets the adjustment) has a large bracket in the rear with a spacer. If you ordered A/C and the rear defogger - the glass with the electric grid, you got the 80 Amp alternator. Here is a shot of the bracket and spacer and bolt from my 73 SD. Both of my 72's had the same set up as well.

BTW, the bracket is actually grey phosphate and not painted.

From what I have seen in Parts cars..., a Combo of AC and Power windows could get this 80 amp set up as well. Just an observation, not saying its Gold...

80 & 55 amp both had them, they were just slightly different.

Bruce - thanks for the suggestion, but this stuff is basically a spray on vinyl coating that can be peeled off. I don't think it will ever get hard enough that it could be scuffed in a controlled. I may end up spraying both the snorkles and the lid.

I did the snorkles today and they turned out well. It still amazes how bad this stuff looks when you spray it on and then it cures and turns clear. It also seems to tighten up as it cures. The air cleaner lid looks even better today than last night with a smoother finish. Here's the snorkles.

Interesting information. Thanks.

That's cool!

Come back to post in a few threads.

Why did you use the green 6484244 ('73-up, think EGR) sensor instead of the correct black 6484242 ('68-72) unit?
I thought the '70-2 RA vent pipe tubes had the bend and went away in '73 (which had an angle cut on the end). Yours looks like a newer ('77-9) unit.
