There is some grazing on my windscreen and want to replace it.. but there is an option for 1/8 thick... or 1/4 thick left and right windscreens. I have to pre-order and it's special order so that I can have it on hand for the swap and I can't pull it off to tell. Anyone happen to know what size is the original? Great Planes seems to think that after 1974... it was all 1/4 but the parts manual seems to say 1/8 and LP Aero ones from Aircraft Spruce just give you the choice. Thanks!
