All Fiero windshields are the same. Old blades dry out and squeak, while new blades don't. Rain-X on the windshield helps too. Just make the glass clean before you apply it. I have found that with wiper blades you get what you pay for.
How long do you want/expect 'em to last? I expect to get a year of streak/noise free and anything beyond that is just a bonus.
I'd recommend something with teflon on it, that should prevent any squeaking. At least until the teflon wears off. I just put some Goodyear teflon coated ones on my wife's new-to-her car, and they work well. Cost about $8 each.
I don't mind paying up to about $10 each, once a year or so, but if that bothers you, have a look around for some that you can put refills in. Should only cost a couple of bucks every year to replace the rubber in 'em. Might be able to do so with your current blades.
And I can second the previous post on making sure your windshield is clean(heavy duty degreaser, don't get any on your paint and make sure it doesn't say "don't use on glass") and putting on rain-x. I'd say it'll act like a lubricant(with the aid of water) and keep things quiet/smooth.
I always get mine from the [GM] dealer. (I realize that Anco makes them.) Metal wiper blade with the correct refill that looks factory. Not the cheap bulky plastic one's found as replacements. A few dollars more with my discount, but worth it. Plus they seem to last longer, but I always use Rain-X washer fluid.
I think i'll try a combo approach using all the posts.-clear glass with degreaser(for glass). a little more expensive blade,apply rain-x, put rain-x in the fluid. for the going faster part--- well yeah ! thanks
I have never found any wiper blade last a year on any car. My Fieros stay parked in a garage and see limited use and the wiper blades just stiffen up because of limited use. I just put on a new set of blades periodically.
I was having problem with some relative new wiper blades made by Michelin. Tried a glass cleaner that is like a rubbing compound. Works very good takes all the residue off the glass including the water spots. Did not help, RainX did not help. Stumbled across a thread the said Michelin have a tendency to chatter. Replace with an ANCO blade and problem went away and is still gone after about a year. The blade lengths were 24 and 20 inches. With that being said the Michelins work well on another car that had shorter blades.
For the daily drivers I change the blade about once a year. For cars less driven, I block the blades off the windshield so the blade does not take a set. I don't know if it helps, but it makes me feel better.

If you are not looking for the car to have historical blades I would suggest the RAIN-X Latitudes blades. Yes they are expensive, but you get what you pay for. I use them on all the daily drivers, and they are amazing. You can usually find instant rebates if you look for them on sale.
I also came across a Good Year version they sell at Costco and they were pretty much the same, and very reasonable on price.
Both lasted about a year, and i decided to change them, but they were not chattering at all, just not wiping as perfect as I had used to be treated to.
