VERY IMPORTANT. Part no#10 the PLASTIC Handle. There is a small plastic nib on the narrow end. If your handle has been used before it will be slightly sheared off. I did not have a new handle to replace the broken carrier at the time. So, I used a small self taping screw and pre drilled a tiny hole in the nib. When screwing tight remember to leave a small bit of slack so the handle can snap back into place after opening the door. Mine is working out fine. Of course, my 88 &89 E-30 rags have original handle mechanisms.
