Seafarer wiper blade

Are you looking for the blade or the whole arm? I believe it is just an AFI replacement @ BW or West.
 
Yes, it is a truck blade (like semi truck not pick up truck). I got a set from Ryder last year. Much cheaper than going through Grady White as I recall. I'll see if I can find the receipt and give you the exact part number.
 
I need a new set of 2 also. Cheapest I found was $25 per blade for the Grady replacement.
 
Same place I bought my blades from. Just remember not to tighten the mounting screw to tight. The blade is supposed to flop when it changes direction.
 
I just took a blade off and went to Pep Boys. Found a match and installed two new blades. They work perfectly.
