2 piece driveshaft angles

[w00dst0ck]

I know it's been covered. I've read the threads, but there never seems to be a real clear answer.

Choppin block kit
Gen 5 L83/6l80e
10bolt

Measurements are as follows.

tailshaft 7 deg down
driveshaft 1 1 deg down
Carrier bearing with 3.5" spacer
Shaft 2 12 deg up
Pinion 7 deg up

I initially set the rear end up for a 1 piece, so I did opposite the tailshaft, but we can't fit a 1 piece so had to build a 2 piece. Now I need to know if my pinion needs to move or not.

From my measurements the working angle between the first u joint and shaft is 6 degrees (7-1)

Operating angle between shaft 1 and 2 is 7 degrees (12 + 1) Then first angle minus 2nd (6-13) = 7 degrees

If that's correct, my pinion is dead on no? Or should it be 7 degrees down?

Any 2 piece frame laying gurus care to chime in? My PB setup when I built my other '65 was a LOT easier since I used a 1 piece.
