Ok, ya'll are going to love this. I have a friend who rebuilt two Stanley Steamers and several various 1920s Rolls Royces and Bentlys. He heard about my problem and has offered to help. He NEVER touches anything that is younger that 75 years old.
Turns out his parents bought new a 1970 280 SE Sedan and helped them with it through almost 20 years and 260 thousand miles of use.
