I don't know the part numbers either, but I will put a plug in for Gater Blades. I have the G3's on my 54GT and the performance is GREAT. I've said it in other posts and threads before but I'll say it again here; I've had decks from the triangle style, to QL style, to 83 series, and now I've had the 48/54GT style. Not only are the deck shells great, but combined with a good set of blades, you can't beat it. I don't have any wind-rowing problems, either, and I use the mulching blades with the high arc like pictured above. Give 'em a shot, they are worth the money!
