I ended up using the cam and crank sprockets, guides, and tensioner from the 85-95, and the chain only from the 84. Then it went together perfect, Im not so bothered the guy charged me for the extra chain and wouldnt let me return the one that was too short because Im finally getting it done. Ive taken the power steering apart 3 times now looking where that bracket might fit. I cant see how it would though. There is one hole in the face of the block right next to the timing cover where the water pump is on the driver side, there is an ear under the square bracket the pump actually sits in, and I cant find any other holes that haven't been used yet. The bracket has me perplexed. The only thing I can think of is that it is some sort of support between the alt, the block, and the ps bracket but I cant figure out for the life of me how it would go and cant remember either. It all seems to bolt together fine without it.
PS the bracket looks like a slingshot, with one welded nut on it.
