Go on ebay and type that length in .025" increments. Your search should be nascar pushrod 9.125". You may be surprised how cheap you can find a double taper trick of the century pushrod made by companies like manton, trend and some of the same sold under another name such as cv products.
Its a long shot when they are this long. But, I have bought double taper high radius 9/16" pushrods for $30 for set of 8.
Career best 8.02 @ 169 at 3050# and 10" tires small block power.
