Fc pitman arm lengths

I HAVE A McKINNEY FC CHASSIS WITH SPE STEERING BOX, QUESTION IS DOES ANYONE MAKE A LONGER PITMAN ARM, AS MY STEERING ROD IS JUST TOUCHING MY HEADERS ON FULL LOCK, MY PITMAN ARM IS 5" CENTER TO CENTER, ENG IS STANDARD DECK JP1
THANKS

How close in to the chassis is the drag link? I bent my pitman arm out slightly to put the drag link on the inside. I also put a slight bend in the drag link just about 10" from the pitman arm so that it is lower all the way along the chassis. If you put a longer pitman arm on you may need to put steering stops on as well so that the front wheels don't rub on the chassis at full lock. The steering box does a good job of limiting maximum lock (I'm using an SPE box as well).
