What are the windshield wiper sizes 1989 Toyota Corolla?

The 1989 Toyota Corolla has some fairly unique wiper blades. Be sure to accurately measure the lengths and also know exactly what the wiper arm attachments look like - its called a "2-screw bayonet" which most or many replacements will not attach to. Also try to get a feel for what an inch or two shorter or longer would look like (will they still pass by each other or will they flop off the glass). Then hit the stores... You need a 20" and an 18" that will attach to a 2-screw bayonet arm.

I did find you winter blades though - see related links below.
