You might save on Invar if you can get away with using coupling nuts to reuse your short rods, and don't forget the jam nuts. I've done it with no measurable degradation.

Someone cut the rods off when it was originally on a commercial frequency. The rods in my duplexer are so short that it will not tune below 147 MHz before they disappear inside the top of the cavity. I can get some dimensions for you to see if the ones you have may work.
