Is there a reason you can't do the MS cable operated clutch conversion to your current 3sp (I'm guessing) as it only operates the clutch fork? That would give you time to save/research on finding a proper T5. I wouldn't rush to use a less desirable 4cyl. T5 just to get it in, you may regret it later.

TMK all of the starters are 2 bolt so clutch size should match the trans/bellhousing. You'll also have to match the oz. of the flywheel to the harmonic balancer as the later model (T5) have a 50oz. balancer/flywheel.

Edit: Started thinking about the clutch size issue and I'm guessing you're planning on mating your 6cyl. bellhousing to the T5 which would be why you may have to use a 9" clutch?

For your 66, 6 cylinder, (assuming 200ci) to convert to a T5, the 93 or earlier 4 cylinder transmission will work just fine.  Billy Walton has one in his 66 behind a V8 and has had no problems.  To install the T5, you will need to modify the existing bellhousing using an adapter plate (I have those), relocating the pivot stud to the passenger side and adding a cable stop to the outside of the bellhousing front edge.  Use a 90 5.0 release lever and bearing.  Use a 92 Ranger 9" pressure plate and your existing (or a new replacement) clutch disc. The existing flywheel and starter will be used.  I can advise in more detail about the bellhousing changes when you get closer to actually doing it.

Once all that is done, the cable clutch setup is no problem and will connect right to it.  You will need to have the driveshaft reworked to fit.

You can add the power brakes after the cable clutch is done so the original clutch linkage won't be in the way of the booster.   If the original drum brake master cylinder is working OK right now, I would continue to use it with the new booster until you convert to discs later on.

You are on the right track with the 5 lug conversion.  Do the front and rear at the same time. 

If you have a V8 conversion in the future plans, I would NOT do the six cylinder T5 conversion, but rather just wait until the V8 goes in.  The money you spend on a V8 T5 bellhousing will be alot less than what you will spend to modify a L-6 bellhousing, even if you bought a brand new T5 bellhousing.

Deb did the T5 conversion in her 66 coupe with a 200 L-6, installed V8 brakes and a 8" rear with 3.40:1 gears. That car was a blast to drive and got over 30 MPG highway.

 

You cannot use the Ranger clutch disc because it has too many splines on the shaft.  I have one rebuilt drum/drum master cylinder that I will give to you if you buy the CK-165M setup.  Then you can chunk it when you go to discs.

Phase one looks like a good plan.
