Bill:
Log onto
www.holden.co.uk and go to e-catalogue, then "wipers and washers". Then go to "spoon type" blades and you will find exactly what you want. I have a set and they are beautiful. Part # 040 309, about $10.00 bucks US.
I have ordered tons of stuff from them and delivery is fast and the shipping very reasonable (usually about $5.00) (From the UK!)
Patronize them when possible. Great outfit.
Take care.
