This door bar option can be ordered only with a MMRB-1.1 through MMRB-1.3. Add this item to your cart when ordering the roll bar to get the low door bars added to your 4-point roll bar.
Low-slung door bar installation photos in a 1979-93 Hardtop can be found here.
Does not fit:
1979 and some 80 Mustangs due to interference between the door bar and the interior door handle. After installation of the door bars, the handle will clear them, but the handle can not be moved enough to actuate the door opening mechanism. The door can still be opened by the exterior door handle.
