I am new to this group and have a question about pinion angle and how to set it up right.

I measured the rear axle and I got 5 degrees down on the yoke . This is the vertical measurement.
I measured the driveshaft and I got 0 degrees.
I measured the at the harmonic balancer and I got 5 degrees. This is the vertical measurement and this makes the transmission tall shaft point down.

DO I have the right pinion angle on this car???????

If not what do I have to do to fix it right.

This is a 1940 Ford coupe ,ZZ4 350 Motor,Th350 Trans w/leaf spring rear end.
Thanks for the help
