Wiper arms and blades came in, and a few things have been learnt.
I very definitely got the geometry of my new spindles wrong. Barely 45° of sweep!
Not too bad to fix, just means redrilling a hole; and
now that I've put the arms and blades on, I know what my clearances
are, so I know how much to change it. 85° should do it, with the 13"
blades.Pretty sure my wiper sweep was backwards. Again, not too hard to fix, just flip the spindles so the arm is on the other side of the linkage and reattach.
The defender wiper arms I've bought have the wrong crank in them. They're about the exact opposite to what I need; but that's not a massive surprise because my wiper spindles are above the windscreen, the Defender's are below. Another thing that's not too bad to fix, as they're only steel. I can cut them off and weld them on at a different angle. Customising the part is a damn-sight easier than building it from scratch! And they were cheap.
...yes, I know this is a bit silly, focussing on the wipers when I
still have gaping holes in the cab that I need to fix But I'm rolling
with what my brain permits me to do, and it's still things ticked off
the list.
