I found a top loader for a great deal which I will be fitting into my 55' Tbird.

My first question is the speedo angle drive, Will this bolt straight in?
And how much exactly does have to be removed from the input shaft? What length is std.?
Is the spigot bearing any different in diameter?
Will the shifter poke through the original hole in the floor?

The angle drive that the 55 had will not work in a toploader (assuming later than 56 trans).  Completely different design (exception 57 O/D trans).
You will have to use a 57 or later cable.  If the clearance is such that the cable will not go into the trans hole, you will have to get an aftermarket angle drive. If that is the case, the design may be that you can use the the 55 cable.   I put a C4 in my 56 Bird, and the clearances were such that I had to do just that, although I had to get a longer cable that was of a 55/56 design (ends).

In putting a toploader 4 speed in my 312 powered 54 Ford, I had to shorten the input shaft about 3/8 inch.  You should always measure this to make sure of the amount to be removed.
Im not sure what you mean by spigot bearing, but if you mean the front bearing retainer it has to be turned a tad (again measure the hole in the bellhousing to get the correct dimension).

Don't know about the shifter location.  There are various tailshafts available for a toploader that have different shifter mounting locations - David Kee (toploader expert) can help you with this

what about the spedo rotation,i instaled 563speed into a 57merc and the spedo cableturned the oposit direction. recently was given a 56ford spedo to use for parts on my ranchero and the 56 turned oposit to 57.reaso being as i contiplate puting a 5spd in my ranchero and need to know what dir. the spedo turns,tho the plastic gears ar easeyer to get.thanks for any help

The spigot bearing is the pilot bearing in the crank.
Maybe a floor mounted shifter might be an option like they put on the Falcons here.

I did a top loader (the odd ball Granada that's an o/d) some years ago. As I recall, we had to modify the mounting brackets a bit. But the shifter came out at the stock location. I think the shift rods had enough adjustment, but we might have cut the threads a bit longer and shortened them afterwords. I used a Hurst Syncho lock. We built a little sheet metal "box" to cover the shifter and mount the boot. But the carpet had enough give to go back down. I think the shift lever was the real short one, for early Vette's. At least back then, you could spec the brackets for the trans, and the shift itself separately, so the Ford brackets with the short short lever.

I've had better luck with trans mounted shifters than floor mounted. There's more noise, but everything stay in alignment. I know you're not going to use full throttle, or shift hard, and 'bird motors never move around on the steady rest.

The angle drives can be bought to drive the same or reversed. They can also be built with a increase or decrease in speed, in case the trans gears aren't available in what you need to keep the speedo accurate. With both trans on the floor, you can figure that out.

It's been too many years and too many projects to remember for sure. But I think I might have used a 12" cable extension on the drive cable. Something from an early Z28 Camaro. Over here, it was cheap and available.

If you use a small block toploader you will have to shorten the input shaft slightly. If you use a big block transmission you will not. The 57 speedometer cable should work. The throw out bearing should work unless you use the large input toploader. With that you will need the 428 bearing and retainer and either use the 428 throw out fork or modify yours by splitting and widening it slightly. You will also need the clutch disk to fit the large input shaft. The stock Hurst shifter for the toploader can be made to fit by modifying the mounting bracket. Think I had to space it towards the drivers side and move it back and lengthen the shift rods. It is a case of crawling under the car and making it fit. I also cut off the Hurst handle and welded on a T Bird handle. It comes thru the stock chrome shifter plate after you gut it. Think I had to raise the shifter slightly and grind a little off of the bottom of the shift arms on the shifter to clear the frame. It is tight but will work. Stock rubber boot makes it look like the 3 speed is still there. If you want the shift pattern on the knob use the Mustang toploader knob with a bushing to mate to the T Bird handle. Took me a week or two of my spare time to make it work. Started with the engine and trans on the stand and dry fit it all in the car before I dismantled the engine for rebuild. Still working on a lot of details before assembling the engine and putting the engine and trans back in the car. Oh, you also need the front driveshaft yolk off a C6 or 57 Overdrive driveshaft for the large input trans because the output is also larger. Driveshaft length should work.  

It is a small block top loader. Out of an 60's XR Falcon GT
1-1/16" input shaft and a 28 spline output shaft.
31 teeth on the second gear which makes it the wide ratio box that I was looking for.

Are FMX outputs 28 spline?  
  
I'm thinking of modifying the original shifter, yet I have seen a nice one on Ebay "Renegade" its a sequential shifter.
I assume they cam the linkages?

I never ran into a rotation problem.  I can only surmise that the hole for the speedo gear on the trans is on the opposite side of the trans than what came factory .

Besides teeth count differences, there are differences in the way the teeth are oriented - to the left or to the right.  I don't know which came in a certain trans.

Assuming this, the pilot bearing/bushing in the YBlock crank was the same size as the toploader trans, id wise.  I used an original YBlock pilot bearing/bushing

I am running a 3 speed big block toploader behind my 292, the speedo drive exits on the 
left hand side of the extension housing; the only place i could get the l/h drive gear was from him.
