Went through this with my Challenger (Pin style), I found these:
Do yourself a favor and get the Trico classic, very close to original and only $20 from local parts store.
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.
