[Mark IV]

Unless you split the trans case from the tailshaft in the car and snake it out, transmission removal in a "little Bird" requires the engine be pulled. That said, it is not a big job, just some hoses and a few bolts and it's on the floor.

Do some 55-57 parts vendors searches and you will find most everything you will need if you have a decent, solid car to start with.

Do understand that the little Bird is NOT a "sports car" and is in reality a 1954 Ford that is chopped and sectioned and drives as such.
