Driveshaft dimension

[Agapo]

Hi everyone,
I'm currently building a truck with a 2.3L ecoboost and MT-82 transmission. Right now I have the engine and trans mocked up in the chasis with the oil pan flush with the bottom of the chasis and as forward as possible to improve footroom. I have some questions.
With the V8 build's is engine oil pan flush with the chasis?
Can someone take a measurement of the transmission output shaft center to the floor or to other reference point in the chasis? I need this to figure out the Mt-82 mounting brace to the chassis. I attempted to post pics but I do not have privileges yet.

Thank you!
