No promises, but Bill Bryan seems recommended in the Orlando area according to this NASIOC thread http://forums.nasioc.com/forums/showthread.php?t=303203

Bill Bryan Subaru Winter Park | 1001 N Orlando Ave. , Winter Park, FL 32789

They have an online form for ordering parts. "It's easy to order a part from our extensive parts selection. We'll get right back to you with availability and pricing." Can't hurt to ask, although I doubt they'd have it in stock.
