Hello all, I recently bought a 64-66 grille support for my 61, the seller told me all I had to do was drill some holes for it to work, but the contour of the surface where the grille sits looks different. Can anyone tell me if my grille will fit in the later support for sure? I know I could pull my grille out and try it, just hoping someone out there knows for sure. Thanks for any help. Ken.
