[TR] TR3 wiper motor

[Frank Fisher]

looking at a wiper motor rebuild for my buddy.
his car is late TR3 1962ish
all
of the wiper motors i have seen have the red wire that goes to the round
circle thing (that controls the park placement) come out of the body of the
wiper motor on its right side as you look at it from the front of the car.
his
red wire is very long and looks like it has to come out of the motor on the
left side where the hot wires connect to.. the red wire is considerably longer
than mine on TS41366.
i cant find a hole on the right side of the assembly to
route the red wire 
through.
was this a later modification?
motor was already
in pieces when it was entrusted to me to rebuild.

also when replacing the
bushes. the new bushes have small "V" groves cut in 
them.
groves to the
commutator or to the housing?
if groves to the commutator are they parallel or
perpendicular to the groves of 
the commutator?

thanks Frank
