1964 Chevy Impala part wanted

I am desperately looking for an original passing gear linkage assembly for my 1964 Chevy Impala. I am looking for the rod type passing gear linkage(the original). not the cable wire version. Along with that, I need the mouting brackets and any bolts where it mounts to the engine near the carburetor and the pivot bracket where the two or three rods connect to go down to the tranny. By the way, it is for a 2 speed powerglide transmission; almost everything on this car is original.. If you can be of any assistance, please e-mail me back ASAP at bjs2287@cox.net. Thanks again, ~~Brad
