Driveline angle questions with Speedtech components

I have a 9" with a locker in it. I had a TKO in it, put a TKX in it to raise up the trans from 4 degrees down. Didn't think I needed to do tunnel work when I built the car. 2.5 to 3 degrees down I thought was stock. Had some noise from the TKO, still have some from TKX, might be from the rear I guess.
Thanks for the response.

I think any time you have the pinion higher than the transmission with the transmission pointing down it’s going to be a problem. That’s a classic example of when the transmission needs to be raised. Either that or raise the ride height.
