Could some one please answer the following questions
The Water Manifold blanking plate seared a bolt upon undoing the bolts could anyone tell me what thread and size of bolt it is , so I can drill out the broken part and re thread very carefully !!

I have been working on the wiper motor today to convert it from Left to Right Hand drive, and have been following Mike Cassidy advice. When I came to switch the two wires as he advised, on my Wipermotor which is a series one 1964 3-8. There was three wires 1 Red to the left and 2 wires to the Right one being Blue.
Do I switch both wires from the left to the Right or just one ?.
Sorry about the poor Photos could not get the camera to focus close up
