ARPLAST replacement blade

[Paul & Lindy Huber Seldom Scene Farm <sscene@lex.infi.net>]

I have broken a blade on my three blade Arplast propeller that I have 
on my Air Creation GTE 503 trike. I can not fine anyone here in the US 
that has a outlet for Arplast. If you sell or know of a sorce for a
replacement blade could you plaese let me know.
 My parts book lists the replacement blade as # 166/48.        
        Thank You,
