I don't know about the 2010 but on my previous 06 G35 I was able to purchase just the rubber blade inserts for about $7.50 each from the dealer parts department. They will insert them for you at no chargelitlmo4 wrote:Ok, this may sound like a dumb question but don't laugh. Besides, I'm a just a helpless female I'm trying to figure out the right size wiper blades for my 2010 G37 sedan. The ones currently on there are 20" (driver side) and 16" (pax side). I can't find any info in the owners manual but through various wiper manufacturers, it gives me 26 and 27 for the driver side and 16" for pax side. Were the ones installed on the vehicle the wrong ones? Which ones are correct? Thanks for your help!
