power steering pump brackets

[68 ReNay]

i've got a '68 with a 350 crate motor. it replaced a 307 that was originally out of a '73 camaro. i want to replace the '73 pump/reservoir with an original "round" typ reservoir in the '68-'72. my 350 has a long water pump and i can't seem to find ANY factory pump brackets that fit a long water pump application. everything on ebay designates a SWP application. did they have long water pumps on the 350's in those trucks? the '73 bracket has that huge elephant ear of a slotted bracket out to the right side (when facing the motor).... it has no purpose for my application. my guess is i'm missing a piece that connects from that bracket back to the motor... but it didn't have it on my old 307 either.... i like the clean set up that the SWP pump bracket has (it wraps nicely around the reservoir and back to the block).

i'd like to find an "original" set up before buying an aftermarket bracket set (like through summit or wherever).

any help is appreciated!
