ok guys heres the deal, i had 2 rh 69 xr7 seats , i have a lh 69 std seat frame upon dissasembly i have found that the upper frames do not have the same inner structure, i thought they all did . i want to just use that frame and be on my way with it. the part that is the issue is that the area that the headrest sleeve mpunts is not there at all. i thought about using some 1 inch square tube i have and grafting it in and using it that way. or cutting apart the other frame and welding that section in . what ya'll think?
