so i've got a 1981 bj42. it has holes on the top of the windshield for a soft top/bikini channel. however, i did not get a top when i bought it. the holes are 8.25" apart and there are 7 of them, with the middle perfectly centered. is this factory? if not, does anybody know what brand would fit this pattern? i'm really not trying to put more holes in it! thanks in advance.
