Power Booster Push Rod Length?

Thank you, Dana. Sorry....what is the M/C keeper?? Still knew at this expensive hobby but getting closer to the end.

Can you reflect on the PB pedal link? Last restoration house gave me an anodized pedal link after install of PB. I don't know which one is correct. It seems measurements are needed at the PB bracket to insure I have all linkages correct. Any thoughts??

Appreciate your comments and replies
Guess what? Figured it out. The M/C keeper is actually the piston retainer with screw. Lot to learn. Thx....Dana
