well, no one wants rusty nuts. guess i'll get the caps as well. thanks.

 

Needed one in a jam as the storms were pounding SoCal pretty bad, and my local dealer only had one wiper blade in stock for $23. Picked it up, and then later found that Anco makes a refill (21") that fits perfectly. $7.99 at Autozone for the pair - bring yours in so you can find out which width is the right one.
