It took me a while to figure this one out,,

I got the empty housing setting with the perches up,, opposite of the normal install position, leveled the empty center section to zero, from there the perches are 5 degree +

because the perches are upside down,, would be 5 degree minus with the perches down as the housing would be installed,,

so actually, good info, I just needed to set up what you were saying,,

and for what its worth, I put the angle finder on the tranny out put shaft,, is a '0',, that is with original OE engin and tranny mounts,, they have probably sagged some over the past 40+ years..
