rear end pinion angle ?

[buds56]

I just set an 87 C-10 rear on the trailing arms with new saddles (not welded yet) on my 61 C-10.

It's a bare frame so there is no spring compression.
My thoughts are to remove the springs, bolt the shocks on and set the pinion at mid shock travel, I'm figuring 2-3 degrees up with the frame level.

I'm curious what others have done in this situation.

Final plans at this point are stock ride height.
Thanks for the help, Bud
