Those from Carpenter come straight. The clips to snap them in place on the top of the door are in the correct location. Making the bend can be tricky. I had an old door glass from my Ranchero to use as a pattern. I took the old felt/molding placed it on the window which was clamped in my vice by the bottom rail. Marked the location of the clips on masking tape. Placed the new part, lining up the clips to the marks and started the bending process. It is a slow process, the stainless will slide in the molding as you push down on it to make the bend. You need to twist it side to side as you push down. You can feel the stainless move, if it does not move the piece will kink. Again, slow and steady with a bunch of wiggling and twisting.
