I have a 1963 Galaxie 500 Fastback. Although I have not opened it up
to confirm, the paperwork that came with the car (I bought it in April)
states that the car has a 9" Ford rear-end and 3.50 rear gearing.
The car is only right-wheel drive. Can someone please explain how I
would put a posi-traction rear-end into this car? Also, could I go
with a higher ratio gearing (maybe 3.73 or higher) and still have safe
highway cruising RPMs on the engine? Please let me know if I'm leaving
information out and I'll be glad to chime in. Full specs on the car
can be found at the link below:
First, it's not 'right wheel drive'... that's not how differentials work.
Second, for you the best bet is to buy the entire 'hogshead' already
built and set up. You must supply the axle spline count for your car.
copy/paste this, both lines:
Yeh, I'm a Krusty old Geezer, putting up with my 'smartass' is the price
you pay..DEAL with it!
A limited-slip differential uses a series of clutches within the
differential to provide traction to both wheels. Historically these devices
were called "Positraction" (GM) or "Traction-Lok"(Ford) - these are just
brand names for the same fundamental differential locking device.
Some good information on this subject is given @

limited-slip ("Traction-Lok") differential @
