[T3] Still would like info on the wiper arms and blades for a73type 3 .

[William Jahn]

Jim, if I under stand correct then the 73 with stock black arms should have the plain nut with a black plastic cap . All I know is at the time I didn’t know there was any difference in arms , since mine were missing on the 73 when I got it.  I’ll measure the arms off the 72 . If they are longer or shorter than yours that will decide what length blades can be used. The way the are now with the right side parked the blade end is very close to the wind screen seal  about ½” away . I was looking at the Bentley where it shows the height on each blade left end should be above the screens seal , with a longer blade if that space is 1 9/16” per Bentley that would bring a 15” long blade higher than a 13” , it’s not much . I do know my blades don’t come near the top of the wind screen . The Bosch black metal blade frames I have, have  no rust and seem sturdy , yet there is no way a 15” refill would fit. It’s been so long I can’t recall if I bought them or it they were on the 72 , I just know I replaced the refills in 2006 and chief Auto handed me a set and they were far to long and I got the 13” ones which are 13 ½” actual.  
                
                The 72 which had the 2 rail seats that also had large knobs so one could tilt them back and would not fit the 73 . The 72 also had a lever that showed when the door was open forget what it was for. Most of the other parts fit the 73 and the 72  had all black instrument faces the only difference was the clock had more number marks and the fuel gauge had different marks , I think the 73 has the marks on the black face and the 72 were different . The actual gauge was the same. 

 When you spoke of plastic blades instead of metal , are they the same type of frame in reinforce plastic or the new single frame that have no extra pivots on the frame yet just a single one piece frame with the blade ?

Up thru '71, all our cars had a silver theme: silver wiper arms, 
blade frames, instrument faces, horn ring.  

'73 cars had a black theme for all of the above.

The changeovers above, and more, all occurred in mid '72, but they 
didn't all occur at the same time. The '72 I had, was very early, 
August of '71, and had the all-silver theme and the early style (2 
rail) front seats.  

It sounds like you also painted the arm fixing cap nuts, since those 
were never originally black. The black arms came with plain hex nuts, 
covered with a black plastic cap, so the nuts don't show at all when 
you look at the late, black arms.

I measured what I have on my '73 and the arms both measure ~13-3/4", 
center to end. The blades measure 15". My parts book never got 
updated that late for the wiper arms, so I can't tell if both sides 
used the same arm. For a lot of years, the L & R arms are different.

Earlier cars, with the arms that pivot from the right side, used 14" 
blades. (At least that's when I THINK the changeover occurred. It 
could have been in '70, with the introduction of the late body 
style.)  

I sold Dave Pallo some 15" blades for his '72 a couple years ago and 
he complained that they were too long; they hit the rubber at the top 
of the glass. I don't understand what went wrong there, but I sent 
him some 14" blades and I believe he's happy with those. I have very 
nice complete (aftermarket black FRP-fiber reinforced plastic) blades 
and replacement inserts in stock. If you're looking for the original 
VW rubber inserts, I have a few in odd sizes that you might be able 
to trim to length.   

In my opinion, the OG metal blade frames were cheap, easily broken, 
and were annoying when they rusted. The modern FRP frames are a 
welcome improvement, althought I admit that I wish they also came in 
silver for our early cars.
