Up for sale is this Saab 900 window crank lever.  This unit is correct for all classic 900 with manual crank windows, from the introduction (1979) till the end of production, (1993)  These also fit 99's with manual windows.

Rarely did US model 900's have these, however the VERY base model 900 cars often did, typically pre 1991, and more frequently pre 1985 cars.

Anyway, these are pretty expensive to buy new.  They are cheap here!  You can buy one, two or a set of 4 here.  They will come with the "covers" too.
