Driveshaft angles

[Jason7121]

Hi everyone I have a question regarding Driveline angles. My truck is a 71 c10 short bed with Ls and 4l60e with trailing arms in rear. I used cpp tubular transmission crossmember. My trans is 6 degrees down so I put my rear pinion yoke 6 degrees up. I don't have any major vibration but the angles just don't look right. When you look at driveline out of trans it goes upward instead of downward. Anyone have pictures or experience with this on your c10. Thanks for any help.
