Just wandered if all GN's show the same thing under Model category on the titles? My hired hand's GN has GRN under model on his title, My title hasn't come back yet but I don't think it had GRN under model on the title.
The MSO(Manufacturers Statement of Origin) and my Nebraska title for my 86 GN list it as Buick Regal T-Type Grand National. On the MSO it was crammed onto two lines. On the Nebraska title it got shortened to Regal T-T.
