AHA, Just as I suspected, my brackets are for a different water pump. I can use the brackets from my 74 chall 360 parts car, they appear to be the same as the front and rear brackets as in 1970a66challenger picture (thank you). I media blasted them but they are pitted pretty bad. I'll have to paint them instead of powdercoating them. I am missing the small bracket that bolts it to the block. I may just look for oes in better condition. Thanks for the help.
