70 Challenger power brake pedal adjustment

I am converting my Challenger to power brakes. I got a booster assembly complete with the swivel. My problem is the pedal is very much lower than the clutch pedal. I know some cars are like that but this seems to be odd looking. It seems as if the linkage that goes from the pedal to the swivel is too short. Do they make different ones for different models? I think this was from a b-body. If that isn't the case does anyone have a suggestion on another way to raise the pedal? Thank you

As long as it doesn't bottom out on the floor,and you have the correct parts, it is supposed to be that way. The book even says its supposed to be that way. So you can leave your heal on the floor when braking, without throwing everybody through the windshield.
