Steering U-joint issue?

[Atommik]

I've got a 51 Chevy 3100, S10 frame, 327 SBC, S10 V8 swap headers.
To get the steering shaft angle correct and to pass thru the headers, I have a u joint on the 3/4"DD steering shaft. The way the u-joint is made, the shaft goes in one end and the comes out the other with a 90 degree different turn to it. For example, if the flat side of the shaft is facing up/down on the u-joint side closest to the firewall, on the other end of the u-joint the shaft flat side is facing sides with the D portion facing up/down. This is causing my steering wheel to be 1/4 turn of center. Is this normal for using a u-joint, or could the joint be assembled incorrectly from the factory. I could probably correct this with some toe in/out alignment, but I don't want to mess up the way it drives, nice and straight even without holding the steering wheel. The steering wheel has a "key way" so taking off the steering wheel and repositioning it is not possible. Any ideas, suggestions?
