No one is currently selling the push button refills in the US - even though they are being made - or at least a batch was made recently.What do you guys use for wiper blades? I got a set of the old metal frames I would like to find refills for. I thought someone said NAPA had them. Stopped there and they said no go. Right now I am running a set that I painted silver so they would look close to original.. I looked at the 'classic', but the back is a single piece and just looks wrong...
exception is 16" which can be purchased from "Classic" under the OER brand.
So the alternatives are old stock or using a universal refill with the clip on the end. Just make sure the universal is wide enough to stay in the claws.
Some A-bodies (not '67) came with "single claw" blades by Trico. I have some part numbers written down from late 60s - not sure if I have any cross ref info or photos. Something to look at on survivor cars.
