Dear Loren and mid-60s Buick owners familiar with the legalize! . . .
Thanks for the link!
Yeah, but I'm not sure it will work on stock blades. I've replaced the aftermarket wiper blades with the reproductions from OPGI, but I never had a chance to see if these refill will fit. So as the old saying goes:
"Your mileage may vary!" . . .
Cheers, Edouard
