I picked up a used TCI Streetfighter transmission for my 67 bird. It was used in a 69 bird. After I installed it and tried putting my driveshaft on the problems began. The drive shaft would not slide into the tailshaft assembly, basically it bottomed out on the internal splines of the driveshaft. I brought the driveshaft to a local machine shop and had some material removed to allow the driveshaft to slide on, I also allowed for pinion angle movement. After the work was done I noticed the tailshaft had an internal bolt hole which got me thinking that it probably had a bolt on yoke assembly with a sliding driveshaft instead of a sliding yoke. How do I straighten this mess out. Change out the tailshaft assembly? Buy a yoke and matching driveshaft? Who makes them? I am putting a 500hp motor in and I don't want this being the weak link.

You're over thinking it. Bottom out the yoke onto the transmission shaft,pull out about 1" for slop,measure,have the drive shaft cut.
The yoke does not bolt to the tailshaft of the transmission,if it did,it's a first for me.

^^^^ and pay them to balance it too.

If you do this with the driveshaft out totally, jack the car up and then let it down on stands ON THE REAR AXLE. That way, the axle is where it would be during ride height. Then do as above.
