Your right Daniel,
Having a '78 and a '69 car gets me confused, and I wasn't going to
dismantle the wiper motors to check what they are stamped with!
I got a driven wheel (larger cog) from the local scrapyard - I thought
it was from a mini, but on reflection I seem to remember it was an
Austin 1100, or maybe an Allegro. The extra few degrees of sweep
certainly does make a difference as you don't get that little
triangular bit of missed wipe in the middle of the screen.
T get them to work smoothly you need to check that the outer sleeve is
smooth, even curves, and not pinched or crushed anywhere.
