Of course cramming all of this into the existing space can present a challenge. One is, with a 4.5" stroke, you don't have room for a stock internal pickup. So the drag link goes through the pan ala Ramchargers. What do you do when the link hits the top of the hole on one side, and the bottom of the hole on the other? I didn't know either, but you won't believe the simple solution if I told you!
