Just don't confuse the pieces you'd need for your car with those that have mostly been discussed in this thread. The OP, myself and a few others were asking about parts for an Early A body, which is 63-66. Your car is a later A body which uses much different linkages. Luckily for you, the later stuff is a lot easier to find and @Dan Brewer can probably supply you every piece of it when you need it.

You beat me to it. Brewers is great. When I did the automatic to 4 speed conversion in my 69 barracuda using a 69 Barracuda parts car, they were a big help.Look further down the list on Brewsters. They have a 64-66 conversion z bar for putting a later style bellhousing with a 10.5" clutch in a early a body. You need to figure out what you have before you start throwing parts at it. The 67-75 A bodies have wider engine compartment and frame rails.
