15' Flex-Wing Alamo Blades Needed

[rutwad]

Hey guys! I am looking for a full set of blades to replace on a 15' Alamo cutter. Part #'s are 02978564, *****8565, & ******8566. Is there a cheap online supplier of aftermarket or OEM blades for this? I did some searching and found some close, but I am not sure the bolt hole size I need.

Just trying to help my buddy save some money. If you guys can point me in the right direction then we will both appeciate it!!

Many Thanks, And HAPPY NEW YEAR TO ALL!!!
