Wiper arms

[climberman]

I have a 66 chevy c10 I bought wiper arms and blades the stainless steel ones the problem is that I live in the mountains and these blades just don't hold up. They don't get he snow off of the windshield. Today the drivers side wiper fell of and there was a blizzard out, a truck past me and blow snow all over my truck I thought I wasn't going to get pulled off the road in time I couldn't see a thing.

Is there a wiper setup that is heavy duty that will fit my truck?

Thanks
