this is a box i made to raise the foot of the main hoop, if the foot was bolted directly to the floor i would have problems removing the rear half of the cage out of the car
trial fitting the main hoop
i bought a hole cutter for notching the tubes but found a good vid on youtube about notching the tubes with an angle grinder which works well, can't fit any more of the cage until i receive the front legs, can't fit the diff until i get the new diff mount, next job will be to weld in the seat rails, rail plates and harness eyes
