Replacement Wiper Parts

[Squid Row]

Contacted Grady White directly and got part numbers but can't find the cross reference to new replacement parts

Boat is a 2003 GW 258 Voyager and I am looking to replace the wiper arm
GW provided the following: LFS581022-2S for the arm and BD721013-18S for the blade

Anyone know where the replacement parts can be found?

The blade is an Anco 52-18...readily available on Amazon. Can't help on the arm......
