yeah, I was surprised also but, Rob helped me figure out the some were not equipped with boosters (as shown in the parts manual) and they (oddly enough) used the 1-1/4 and the different position hole on the brake pedal (shown in Rob’s special book ?)
JSD’s booster being under the hood, led me to think there was a possibility someone added the booster and could have altered or exchanged the MC.
from his little baggie I’d say it Looks like he is good to go.
JSD, if it is “too far gone” they can re-sleeve it. The last one I had done, they didn’t have the 1-1/2” kit….. but your covered there
