8 point roll bar

Put the subframe connectors in first. You may need to cut access in the floor. Dont get crazy with it.
The main hoop should come with longer than needed legs. Tip-if you are going to use plates to bolt/ weld down to grab the sill and rear clip hole saw two holes before you put the plates downso you can size the main hoop legs.
Two biggies: make sure the frame is level before you install the sub frame. Second make sure the main hoop is where you want it in relation to what ever seat you ate going to run and reference thr rule book on head to bar spacing.
