      I modified the linkage like you said today! I actually took about 13-14MM out of the linkage, it might have been too much! I put the linkage into my vice and turned it by hand and it certainly had a full sweep! THank you for posting that information! Free mods rule -- especially when they cost $200+! And I was gonna pay that!!
      Glad that I could help.

        Did you not look at the link i posted? The wiper motor just turns, it's the arms that loop to make it seem like it turns back and forth.
        Yes I did but obviously I wasn't pay attention to well. Looks simple either way.

            Sweet mod for sure.

            So you have to shave about 12mm off part #4?

            Or do you mean the part just above #6 in the diagram posted on realOEM?

            Then its just a matter of bending the wiper arm itself? Gonna do this!

              Have some flat black prepared for when you bend the arm, you have to heat it with a torch to get it to bend right. You also probably need a vice, i can't think of another way to do it.

                I see, I'm sure a blowdryer will do the job, and I got a can of Duplicolor flat black. And when its the wiper arm itself, not any part of the linkage.

                  A blowdryer!? Are you serious?

                  You have to heat the metal until it's near red hot to get a good bend, when you do this, the paint flakes off and discentigrates. But yeah, the wiper arm has a slight bend downward that needs taken out.

                    Well its worked in the past on other projects, so I'll keep it in mind, but my friend has a blowtorch too, so just in case.

                      What the hell did you manage to bend with a blowdryer?

                      I used a propane torch and held it on there for a good 15 minutes.

                        When I was working on my headlights it helped remove the old plaster around the glass so I could replace the broken glass with new glass.

                        Meh I'll use a blowtorch okiez?

                          Getting glue soft is a little different than trying to work metal. :P I've used a blowdryer for things like that too.

                            You're right dude, didn't think about it much. ANYWAYS I can't wait to do this, I always wanted to have a single wiper, but not for the cash it cost!

                              I'm probably going to go back to dual wipers, i'm starting to not like mine, plus the "RICER!" comments get old.
