The firewall was planned by staring at it for about an hour or so and figured the cuts we made were the best spot for when the cab fell the sheetmetal would line up the best. As for the steering and brake booster part buy cutting it where we did the booster stayed in the same location as did the steering box hole. Also kept the gas pedal mounts and almost everything important on the drivers side stayed where it needed. However with z'ing the frame for the engine craddle the steering box hole will have to move up the amount of the z but I'll still have space between that and the brake booster. Thats a good idea for the trans member but sense I have to drop the motor the reverse about of the z for the stock hood clearance I'm just gonna fab up an entirely new trans crossmember. I already have the steel for it in the garage.
