66 mustang swap from 3 speed manual to 1987 GT t5 borg warner, severe vibration in neutral, in and out of gear, vibrates in all gears on road, vibrates with engine turned off coasting, mechanic that installed says tranny bad. Need second opinion

Sounds like a flywheel issue to me(IE: mixing a 50oz flywheel with a 28oz balancer or vice versa) Nothing else that it could be if it vibrates in neutral right? Aside maybe from a defective pressure plate or something of that nature. Regardless, without knowing what parts were used its not likely we can diagnose it from the internetvibration occurs sitting still with engine in neutral
The different pilot bearings result from the different crankshaft hole diameters between the 2.3 and the 5.0(and possibly how the input shaft length interacts with the different engines, IE: some engines have an "extended" pilot bearing to make up for a shorter input shaft) The only way it could be anything pilot bearing related would be if the pilot bearing was just bad(which is possible...I personally prefer bronze pilot bushings most times since there are no bearings to go bad...but pilot bearings are a bit smoother)Correct pilot bearing? There's a different one for V8 and 4cyl T5's. Are you certain the T5 taken from the 1987 is a V8 model? The 4cl pilot shaft is smaller, so putting a 4-cyl T5 into a car with a V8 pilot bearing would create vibration from the input shaft wobbling.
The V-8 input shafts are 0.668 and the 4-cyl are 0.590 inches.
EDIT: Saw that you said it vibrates in neutral? Try this. Put it in 1st gear, and push the clutch in. Does it still vibrate? If so, it's NOT the transmission. That would hold everything in the T5 still including input shaft and the clutch disk. The flywheel and pressure plate however are still spinning.

standard 5.0 pilot bearing, which is designed for a input shaft with a diameter of 0.668"
2.3L T5 which has a input shaft tip diameter of 0.590"
