Lowering change pinion angle?

[cv67]

67 a body
Lowered with 1" drop Hotchkiss springs
Front still sits a little lower than front want it level
If I drop the rear an inch will it change much? (angle)
Just dropping the body down not the frame correct ?Or?

Asking as my trans just kisses the top of the tunnel in a spot or two dont want to make another tunnel or have to change major things. I do have 3 mount points for the upper control arms in rear they are on the middle mount now.

Opinions?
