Hi everyone, I just bought my first old car this weekend and so far so good, but I'm trying to learn as much as possible before I have problems. I picked up a 1949 Dodge Wayfarer Business Coupe with the fluid drive trans and flathead 6. I Don't know much about these old Dodge's but I'm dying to learn. Looking forward to everyone's input! From reading some posts I noticed that everyone is recommending 30W or 20/50 in the motor and 10wtND for the fluid drive trans. Any disagreements there? Does anyone know where I can get a repair manual for the car? Wiring Diagrams? Thanks everyone!
