Cluch and pressure plate help

Wow, this is a bummer. I cannot locate anyone that can supply me with a cluch and pressure plate. 1967 - 273, 2-V, three speed. The plate measures 9-5/8 and the cluch measures 9-3/8 with 23 splines. I would hate to put the old stuff back in. If necessary will a 10" set-up w/ a different flywheel work? If I change to that will the old starter fit?
I'm in desperate need of these items by 3/23. Any help is appreciated.
