I just purchased & installed wiper blades purchased from thepartsplaceinc.com
part# is WW10497Z
check it out. they 18" 7 black framed

How well do they wipe? the Trico 18-2 were my go to but they are no longer available in the traditional looking style and wiped horribly!! lol

I cannot say as to the wiping ability but they look almost identical to the orig that were on my '81 T/A, except for the clip that holds the rubber blades in place . As with my '72 Buick GS, I did not drive from home into rain but on about 10 occasions over 21 year, I did run into rain on the way home. They scenario will apply to the T/A. I recommend them. At least thepartplaceinc is a respected source for parts.
