I know for some 2007 & 2008 GM trucks they now have the old style wiper arm assemblies, going back to the "j" hook style. Do they have them for a 2008 GMC Sierra? We tried the part numbers for the 2007 Chevy Avalanche, but they will not work. The new wipers are just bad.....if someone knows the part numbers I would appreciate it. Again looking for the old style wiper arm assemblies that use the old "j" hook type refills...8 pressure points on each.

Thanks for any info anyone has....
