I picked up the TRICO 47-700 Break-To-Fit refills at Advance Auto last night.
Did a quick test fit to see if they fit the OEM claw. Perfect fit.
They come two to a pack with both 22" long so one should fit the long blade right out
of the box and the other can be snapped off at the 20" mark (the metal splines
are scored at one inch increments).
$6.99 US and your OEM blades are good to go again.

I'll fully install them when I get a chance but don't anticipate any problems.

Thanks to all for your help!
