Went through this with my Challenger (Pin style), I found these:

Complete assembly: Trico Classic Wiper Blade 16" ( PN 33-162)

Refills only: 16" Wiper blade refill (refill only) #60-1614 (Napa)

You can also check Walmart, they sell Pylon brand which has the insert style blades. Just the buy the whole thing and pull the insert out.
