54" Mower Deck 914A Gator Blade Part #?

[Luremaker]

Anyone know the Gator Blade part number for the 914A 54" mower deck? The OEM Blades are 18-1/2"L 2-7/16"W with a 15/16" round hole. I can't find any listing on Oregon Chain's website in any of their pdf's. Even Agri Supply could not find a match.

Are there any blades available other than through the dealer?

It seems Gator does not make a blade for the New Holland Decks. They do have a blade with the same demensions except the hole is under sized. Anyone know how hard it is to drill a 15/16" hole in R50 steel?
