How to get out stuck perpendicular LG orifice for an LP swap

I am swapping my new Samsung 30in 6cuf range from NG to LP and successfully swapped oven, broiler, and all the normal cook tops, but the front right cook top has 3 orifices that need to be changed. One is normal and the 2 others are perpendicular to the cook top. This leaves no room to access them with a normal ratchet set so i bought a set of small open headed single size wrenches (not easy to find 7mm where i am) thinking itd be fine. We will it would have been, and was, for the right perpendicular orifice which came loose, but the factory over tightened the left oriifice and i cannot loosen it even with the correct size wrench. I can get a 6 sided ratchet on because there is no space. สล็อตแตกบ่อย
