This may sound silly, but what would the proper size windshield wiper sizes be for a '99 GTP? I checked the manual and it said 20", and then went into a store that had these booklets from two different windshield wiper manufacturers which said 22" for my car. The more I look, the more I see 22", the only thing that has said 20" is my manual which should be right, but I have my doubts now. Anyone have any brand recommendations either? I'm looking for some premium quality ones.

Mine measure at 22".

I can't remember what kind I have, but I put a set of Bosch's on the wifes car, and she loves them. Maybe I've got Bosch on mine too.

definetly 22's i just bought new ones from fleet farm. I thought they were huge but that is what all the books say. does anybody run different sizes? I have a buddy that has to run a 19 and a 20 inch wiper on his sanoma cause of the curve of the windshield. Check ur owners manual buy my '00 GTP takes 22"s

22s, but my mechanic, when he checked the car out last, said I should put a 21 on the passenger side because the 22 over hangs the glass and is bit too long.

i use michelin's they're awesome and are about $5 a blade.

Yea, my friends always call that one "that flapper".

i just bought a GM blade for the drivers side (ac delco) and it sits up off the windsheild when it goes on that black resting tab...i kind of like it, but im not really sure what to think of it yet...it works AWESOME, but i think eventually may not last as long because it sits up higher, but then again, im not sure...

I'm running Bosch on my GP and Strat. Both use 22" on both sides. The only cars that require different lengths are those with huge driver side wipers and small passenger to prevent them from banging against each other. I've seen cars run a 24" on driver and 17" on passenger. It all depends on what the vehicle was designed for. I think Cavaliers run 20/17.

same here they work awesome for the price. Did anybody see that mr. clean has windsheild wipers? That messed up
