i'm installing power brakes on my 70 challenger. i got the power brake assembly from summit and while it fit right in no
problem, the arm or shaft that goes through the firewall and connects to the brake pedal seems to be about an inch or so short. it doesn't want to let the brake pedal go all the way up and engage the stop light switch. also the brake and clutch pedal are on different planes or heights. there is no fluid in as of yet. has anyone encountered this problem? it is a four speed car that i repowered with a hemi. thanks in advance.
