Just trying to explore my options. It turns out that the check valves had rusted to the seats in the master cylinder. I cleaned all the rust out and now it works fine. The rubber was in surprisingly good condition as well. Thanks to everyone for your responses, I appreciate it greatly. You have no idea how much your tech papers and archives have helped me out. :) Thank you...

At least, you'll know you're getting the right part! Bill Lane #3635
