lookin for 73-79 p/s pump and brackets

[Fast68Chevy]

i need p/s setup (dont need hoses) for '73-'79 small block V8 engines with HD cooling

the style i need uses a smaller bracket that attaches to first exhaust manifold mounting bolt and a bolt passes through the main pump bracket form the front and threads into the smaller exhaust mounted bracket
and the whole setup pivots at top on a stud screwed into the end of head in bolt closest to intake manifold, ,
and also uses a bolt hole in the lower pass side of waterpump casting, most are like this but are a few out there that arent exactly like this.

who has what right now ?

open to any possible parts trading also, i have all kinds of stuff

thanks
