The cowl bar location and then placing the firewall in its proper location is critical for locating the body.

Do note also that some of the people that I have talked to state that they had to cut/trim the upper lip of the of the firewall to get the body to set correctly. With that upper lip being at the angle that it is and also possibly being too long, the body will set high and forward. If it is cut slightly short you can add some bubble gasket material to the top of the lip to seal the cabin area from the engine compartment.
