driveline pinion angle with T5 swap into '66

I'm swapping in a T-5 for my lame-o 3 spd TL. Will I have to use the stock 3 finger clutch system, or I can I upgrade to 10.5" diaphragm setup with the bell crank system? Also will I need to shorten the driveline as I've been told. Others have said there is no need to shorten because it stays within the ,IIRC, 3 degree range on each end. I'll be using the original bellhousing with the adapter plate, as opposed to the T-5 housing and the adapter swivel thing. Sounds like a cleaner option, but I already have the original bell housing and want to use what I already have.

I dont understand... IIRC The length of driveline only has to accomodate movement on the output shaft, i.e.; when rear bottoms out, there must be room left with out the driveshaft jamming the output.

As to angle, they need be equal and stay within (about) 3 degrees with spring travel...if one extends the plane of rotation, how does that change it?

OK, maybe this will be a more clear description of my question. I've heard that the output on the T-5 is "farther back" than what was originally in the car, and I've also heard that it's in the same place as original. If it's farther back, then the angle needed to arrive @ the input on the 3rd member is "steeper". Now if it's in the same place as original I have no problems. If it's not, then, is the angle changed enough to where I will have problems?

And to the other part of the question. Can I use a diaphragm clutch on the original bellhousing, flywheel and bell/crank style system?

Yes you can use a diaphragm clutch. You may need to get a flywheel with different mounting hole pattern. You will like how it reduces pedal effort.

The change in angle is not significant. The important thing is whether the drive shaft bottoms out in the end of the trans shaft on a full bump. Or if the splines don't have enough engagement at full droop. Measure the distance from the back of the bell housing to the end of the 3 speed. When you are done with your swap, make the same measurement on the 5 speed. Change your driveshaft by that amount, either longer or shorter.
