The centerline from the front of the crankshaft to the output shaft on the trans must be dead straight. Get it out of line and you will know it. You get adjustment for the splined output shaft by raising or lowering the rear trans mount. That is why you must measure from the frame (not the floor) to the center of your original trans output shaft before you start. Then when you build your new rear cross member to mount the T5, build it a little lower than the original. Then you can use shims between the new cross member and the rear trans mount to set the correct height. You must get the drive shaft angle from the rear trans yoke to the input yoke of the rear end correct or you will have a terrible vibration and very short lived "u" joints. If you will google "driveshaft alignment" you will see what I mean.
