I've been going through some older posts trying to work out if anyone knows for sure what the XU1 wiper arms are.I have the parts books with the specific number but no pics. I read they were anti lift wipers ( like the Falcon GTs had, the twin wire style) this stopped the wind pushing them off the windscreen at high speed.There was a pic put on this forum of the 72/73 Bathurst XU1, it shows the twin wire type.
I'm asking because I have a pair of trico speedblade wire arms , the same length of the LC blades and same clips,curious to see if anyone has the same type.i will try to put up a pic
LC XU1 wiper blades

Same as all lc, if they're the same as lj. I'm sure that there's no difference. My xu1 has exactly the same wipers as all lj. Gary.

I have been trying to work this out for many years now .
There are different part numbers in the LC parts catalogue for standard cars and XU-1 .
I have studied factory XU-1 cars and standard LC Torana's , enlarged the pictures but can not tell the difference .
Regards LC870

They aren't the twin wire type Sean. I have also done what LC870 has done, and have reached the same conclusion; I can't tell! I have seen two types of arms used on the LC; one is flat, the other is kind of ridged. I think the XU1maybe had the flat type. I only say this because a mate has a pretty much untouched 4 banger SL, and it has the ridged type. But that is no guarantee...I'll see if I can get photos up later.

HI
Me too, I've been trying to find the difference for years. All XU-1s have had part number for the blade assembly as VS11788 from day one to the end of production. I was told a few years ago that the XU-1 blades were 1 inch shorter, but I have no evidence of this or for what reason why that would be.
There was a change in the arms in April '73 to the Surlock type - but that applied to all cars not just XU-1s.
Cheers
Bazza

Just had a good look at the Steve Stathis book on XU1's at Bathurst and disproved my own theory. I'm back in the camp of no idea. I did notice though that HDT and one or two other race teams used the twin wire blades on their LJ race cars. But most used the production blades.

I've been trying to work this one out as well. My theory is that the springs underneath the wiper arm that push the wipers down onto the window are different.

The spring is part of the wiper arm which is the same for all LC/LJ Torana (incl the Surlock equipped arms). It is the blade assy that has a different part number as Bazza has already said.

Finally got some pics up, these are the trico speedblades I have in the first few pics ,the last pic has them against the standard blades fitted to my car now.The green one , I'm not sure of who's car it is , and the Bathurst race cars with them .Im leaning towards these being the mystery part number , not sure though. Just going on the fact that the XW GT had these ones in 1969 , maybe Holden liked the idea ? I have seen footage of an old Bathurst race car flying down the track and its wipers rising off the screen from the wind pushing back off the screen and against the back of the blade.

The wiper blades on your car are the same as the ones fitted to XU1's from the factory (340mm length). As I mentioned, some of the race teams used the twin wire ones, but they are an aftermarket fitment to XU1's. Though maybe they found their way into the parts book as they were going to be fitted. Lots of teams used the 'aero' clips on the actual arms; sometimes two per arm.

Harry probably had them listed in the parts book so he could use them on the HDT cars.

I'm pretty sure that we've covered this topic before & they're all the same, I'm also reasonably sure back to eh used the same trico wiper arm, i marked my xu1 wipers, i haven't measured them against standard lj, but I'm sure a friend has & they were exactly the same, i can't remember seeing them on any holden's Gary.
