goodmark or dynacorn quarter, how to tell???

[redfire69]

So I think I have two different brand full quarters. The drivers fits good and has a round hole for the bumper mount and the passenger seems low and has an oval hole for the bumper mount. All other measurements check out, but the pass quarter is low thru the wheel opening and deck lid area.

Anyone know how tell the difference and identify the brand? The problem is I may have to get another passenger quarter if I can improve the fit at all...

Thanks in advance!!
