Thanks for the tip on Tesco unibody wipers.
I got myself a 22 inch one (and Saab IS listed on the box of that one) but have to say I found it really difficult to fix it onto the wiper arm though. There is not enough clearance to get the U-shaped thing on the end of the wiper arm to slide over the plastic clip and I was about to return it to Tesco but only persevered because at least one person on this forum had clearly managed to get it on. I suceeded in attaching it only by first partially taking out the plastic clip halfway, positioning the U-arm in place and then jamming the plastic clip back into the curve of the "U".
Another tip : Re REAR WIPERS :--
I found it really difficult to get rear wiper blades for my 9-5 Estates. NEO don't stock them, many autoparts shops don't have them and I suspect that Saab Orio parts will charge a bomb for them if they do supply them. However, although Halfords strenuously claim not to stock them for Saabs, their own (Halfords) brand 14" rear wiper (code no. "W36") WILL fit 9-5's of 2006 onwards. You have to get the one with a "stepped" slot in the wiper body as Halfords actually make 2 different types, but confusingly pack them both in the same box!
The Halfords 14" wipers will NOT fit pre-2006 9-5's because the cut-out slot in the wiper body is too short to accomodate the projection on the end of the older wiper arm. I had to insert new rubbers instead into my old original wiper blades. Further tip -- when inserting the rubbers, insert just the rubber strip first almost all the way and THEN slide in the two metal stiffening strips (after giving them a pre-bend convex OUTWARDS from the line of the rubber, for tension and a clean wipe). I intially tried inserting the rubbers with metal strips pre-loaded and struggled!
