Please help! Looking for "Y" in Deuce wheel cap

[RARE Z/28]

Thanks guys,
I knew that the members of this board would be able to steer me in the right direction. Marlin, please let me know if I can help. We have several reputable shops here in Canada as well but I would need an actual sample for them to reproduce the decals exactly. I suppose that is where the problem lies. Does anyone have a source for an original? Or possibly know the whereabouts of an original set which could be purchased? Thanks again to all who have helped!
Richard.
