Stock '68 GTS 340" pinion angle question
There is an angle built in to the perches on the housing.
I get the following.
With the center section of the housing plumb, the perches are 5 deg
I took photos with the housing upside down
So with the housing perches level the center section mounting surface would be leaning back at the top 5 deg.
And yes those are factory welds and this is an untouched OEM housing
Pick your poison...
Housing as mounted in the car, Right side up with perch level on the bench and center section mounting surface 5 deg
Housing upside down on a bench with the center section mounting face level and perch 5 deg
