Will also need the plate for a manual shift vehicle that goes around the steering column. It allows the clutch pedal rod to pass thru the firewall.

As mentioned there are clutch rods, a "Z" bar and the pivot balls that attach to the frame and the engine block allowing the Z bar to rotate.

Oh and don't forget to connect the wires from neutral switch or the car won't start. Some T-5's have a neutral safety switch some don't . Mine didn't so I just spliced mine together.

You will need
A T-5 from a mustang 5.0 prior to 1994
An adapter from John Mummert , his website will tell you what specific year T-5 transmission will work
A manual transmission bellhousing for a Y block car not truck.
A pedal assembly from a 55-57 bird.
A Y block throw out bearing fork
The linkage that connects the clutch pedal to the throw out bearing fork
Y block manual transmission flywheel
Clutch , pressure plate and throw out bearing, all of which I bought from Mummert at a very reasonable price. Use a diaphragm style pressure plate lot less pedal pressure.
A T-5 , AOD or C4 yoke for the drive shaft
A new drive shaft, I used one from a mid year Corvette that worked fine , Just something I happened to have in the shop.
You will need to build a cap for the top of your tunnel where the shifter pokes through .
Speedo cable I used was from a 1957 Ford.
A 21 tooth speedo gear .
A 5.0 mustang transmission mount, some modification to the stock trans cross member , T-5 mount will require drop of about 3/4"
Those are the things I can think of off the top of my head.

Petew.  THANKS for your follow-up with the driveshaft yoke information, Pete.  Methinks your '55 'Bird has the original '55 / '56 Dana 44 rear end, correct?

Again, a NICE (very professional) looking installation!  I'd encourage you to consider submitting an article to Bruce Young at 'Y-Block Magazine'. 

Regards,

1310  and 1330 are the ujoint physical sizes . the 1310 is what I used on the front of the driveshaft , its pretty tight in that tunnel and the 1330 would be a real tight fit. On the back you need a Neapco 2-0291 which is a conversion joint . It is a 1310 joint on one plane and the "winged" style on the other plane that is required to bolt up to the tbird pinion flange.

To my knowledge the two types are of a small or large Uni joint option, as is found on the diff yoke.

Petew.  My question about what front driveshaft yoke you used is triggered by seeing two Spicer numbers for the T-5.

Both are 28 spline and apparently are used for T-5, C4, Ford Toploader, AOD, and AODE (whatever that is) applications.
One Spicer yoke number is 1310 and the other is 1330.  I haven't gotten a handle on the difference between the two yokes yet.

Your shifter looks great!  Thanks for the driveshaft length info.  I wasn't clear what I'd be running into.

Isn't it amazing that the T-5 only weighs 75 pounds.   Smile
