How bad would it be to run this box off of it's center point? As it stands, in order to make everything correct under the car, the steering box is turned 90deg' to the right off of it's center point.

I am thinking that the main shaft on these boxes is cut incorrectly, as well as the mounting ears are welded wrong.

Or!

They knew all the shafts were cut incorrectly, Didn't want to eat the cost of making new ones and decided to try and fix the problem by welding the ears for the boxes out of time to move the box more in the direction of the offset (wrong) cut center shaft.

The byproduct of this is that now we have the terrible angle from steering column to coupler.

As I think about it, if I were to remove the shim in my box, it would make the coupler impossible to get on the shaft, however doing so would fix all the centering issues.
