I have a set of both OE & repop arm frames made by Trico. When I had the Harwood hood on the car modern ones didn't fit well under the back edge even after trimming it. On stock hood they don't like to always make their was under on the passenger side.I miss the old wiper blade inserts you put in existing case.
Height of the new blade assemblies is the issue I have rubbing my non stock hood when retracting.
