360 push rod dilemma

I recently purchased a pretty nice street worthy 73 Dodge Dart Sport. Used to own a couple back in my teens. I started to repair a head gasket leak but instead decide to pull the engine to to do a paint job which has now turned into a complete engine overhaul thus opening up the dreaded can of worms. I know nothing about this engine other than its a 72 360 which I believe is pretty standard. It has had replacement CAM with hydraulic lifters however its a mystery to the exact make or model. Upon taking it apart I found one of the pushrods slightly bent. What I thought was going to be a easy fix has now turned into a search and rescue mission. The pushrods are not your standard 3/16" diameter pushrods they are solid 9/32" diameter rods with dome ends. As you can see in the attached photo they also have a strange 7.480" length. I have searched most major restoration parts sites and have stuck out. Does anybody have a clue where I might be able to locate some 9/32" diameter replacement pushrods? Thank you
