Yes there are 5 in the bottom on the car side and 5 screwed in the back of hardtop frame to match those, and 3 chrome ones in the front top. Yes the trim needs to come off. You might be able to make the back ones for the car and for the hard top, all 10-- plus they might be available. It is just some mild steel with 2 – 90, degree bends for a screw to hold it in the back ,and all 5 bottom ones are the same.
There are 2 types that fit on the top for the back upper and they are all 90 degree L shaped. The 3 along the back are smaller than the 2 that go next to the door above the B post, but they are all similar 90 degree and easy to make.
You have to drill the windshield frame for the chrome top ones it is made of chrome plated brass.
One thing I learned the hard way was that with the hard top on the car, the side-curtains sit about an inch lower and have to fit in the hard top frame opening or the door will not close.
