more good infomation !! the 440 in my satalitte with current cam idles in gear with foot on brake at 10hgs of vacume
thinking of buying this booster to fit with none power drums
seems a better deal sourcing the midland & ross booster , master cyliner / fire wall plate & pedel bell crank linkage !!

thanks again !! for all the feed back !! given me some things to think about
