Mine is a little more elaborate than an 8 point. However, no matter how we placed my door bars the X ran tight into the inner door handle (without putting bends in the bars, which do not meet spec). So, I made some block off plates for my door panels and used the inner door handle kits for fiber glass doors and made the handles come up through my armrests. Works great and can still reach from seat when belted in. Picture 2 shows them better.
