In the past there have been a couple of guys that said they had genuine 292 brackets. I see so few 292's, that I never bothered to even look.
I modified this one from a 70's Camaro 250. The first scan is from a Haynes, 67-82 Chevy manual that I found at a swap meet for a couple bucks. Not real sure if they have the PS belt on the inside or out of the Alt belt. Mine worked as you see in the pictures.

This next picture is the area that had to be modified. A lot of material had to be removed to clear the by-pass hose. You can see part of the weld where I cut the bracket apart and added a filler piece to acomodate the extra height of the 292. I trimmed a lot of material from the back of the bracket to clear the headers. This area may have had a brace that went over to the side of the engine. I don't recall and it has been this way for several years without it.

To the left of the by-pass hose, you can see part of the upper bracket that shares two bolts(longer) with the thermistat housing.

The alternator adjuster bolt ties everything together and is adjusted before the PS belt.
