Alternator/pulley Wheels Brackets

[codyssilveradoz71]

Hey, well I found out what year and what size my motor is, its a 350 5.7L, and that is the original motor. I found the casting date stamp on the block, and it reads E0970-May 9, 1970, I dunno if that was when the block was made, but I googled the casting number and it brought up a 1987-1988 5.7Liter 350 V-8. So, I also put this together, I did buy the right alternator, but the motor has either the wrong alternator brackets, or the brackets are bent, I know one bracket is the wrong one. And that is the front one that mounts the ac unit and the other top pulley wheels, so if anyone has this bracket for an 87-88 350 v-8 silverado, and also I need another alternator bracket, I need the one that mounts on the left side of the alternator, if you were looking at at it from the front under the hood, then it would be on your right side of the alternator. I know that this alternator is supposed to be bolted in with 3 bolts and 3 mounts. So I need the two mounts for the alternator as explained, so please let me know. I really want to get my truck running, but I just need these parts. But if I can get these from anyone off here, then I'll be going to the salvage yard to get them and the fuel sender unit, just want to see if anyone could help me out with these parts. Well let me know
