Replacing dew wipes is something that every Fiero owner will be doing or should be doing. Its a real PITA job but after you do the first one the next one comes easier. I choose not to try to change the dew wipes while the window sits in position. Instead I mark and remove the window stop brackets and raise the window up to where the difficult screws can be accessed with an ordinary screwdriver. I've seen how others do it with the window sitting in the normal up-down position but you need to be a contortionist to get at those center screws.
Until DIY Stu and/or Sejal begins making them again the Fiero Store is the only source. The dew wipes can also be made from stock dew wipe material but you would need to drill them, re-use the mirror bracket, know how to flush rivet and buy some window felt separately. It can be done for about $50 each but IMO not really worth the effort.
