There's a much easier way which basically works as good. Basically just keep the centre wiper and just rebolt it on at a similar angle you shown and test. You may have to tweak the position a little to get the wiper to clear the most of the windscreen possible. You also may have to shave a little bit of the cowling where the arm may hit
on my r31 the side wipers linkage broke so to get me by in the middle of winter i just re adjusted the centre one to reach more of the windscreen by doing as stated in elliots comment uuntil i had time to get the parts and fix it properly
Or just use a rear motor from a few different types of cars. Nissan cube, ford freestyle, ford expedition. Will all work on RHD cars. Im building the only 90s model RHD Ford Ranger in the US and a mono wiper conversion is the only way i can go without more fab work. Since im doing everything on a stock LHD firewall i figure why do extra work. Those 3 vehicles use a rear wiper motor that all have a large sweep. Best of luck.
@@Randaljoness good luck .... I scored a new in sealed package bonrath wiper for 315ish us dollars. But also have a second one from a company that makes Porsche aftermarket items these days in the mail also new. It may pop up on eBay sometime this spring if I don't buy another mk4 by then
Bonrath doesn't build those since a loooong time... I just scored one for my mk4 TDI and the quality of a well designed and developed wiper kit vs any! Diy improvisation or imitation more so; is in my opinion well worth the money.
