rally wheel questions

Hi all,

I have a set of trim rings on my rally wheels but I am not sure if they are mopar or not. Below are some pics.

I also have a few questions.

1) My wheels are 14'' x 7'' SBP rallys and I need to know what the correct trim ring width is? The ones I have now are 2'' wide but they dont really look like they go deep enough in the wheel.

2) Do all mopar rallys have a hole for the valve stem or do some of them have a U shaped opening for the valve stem.

3) Is the outer edge of the correct trim rings flat only or is there supposed to be a contour where there is a flat edge with a narrow lip as well.

All your help is appreciated.
