Pentax 67 parts

Anyone know where I might be able to track down at least one of the screw/studs that the prism fits onto?
I dropped the camera (in a padded bag thank goodness) and on impact the prism sheared off one of the screws and bent the other one a tad. I've been watching eBay and short of buying another body I can't find one.
Thanks
