thinking about it i did not have a slotted bracket. old man memory here. i made a part of the new bracket fit tight against the alternator so it would not rotate. the bracket then fit the back of the standard block bracket. but its a PIA to get the nut and bolt back there and as i recall i could not get a nice long one piece bolt to fit. if i need to i can stick my camera down there and shoot some pics for you.

Paul's conversion came with a machined front pulley for the wide belt. building a bracket to support the rear of the alternator is a little tricky but certainly not out of your realm. you will see the mounting hole on the back is not in line with the front. your new rear bracket must have a slotted adjustment hole. when i put an alternator in my TR3 i used the pulley off the standard generator. machined it to fit and built a special nut. but in doing so i pushed the pulley forward of the rest of the pulleys by about 3/16". so i was forced to grind off some of the aluminum mounting tab of the alternator. again i build a slotted support for the back of the alternator.

He would like to know a specific GM application for the donor alternator (to get the right terminal orientation, etc).
