NP205/Transmission Adapter Measurements Request

A) The vertical distance from the crossmember mounting surface to the centerline of the transmission output shaft

B) The horizontal distance from the transfer case attachment surface to the centerline of the crossmember mount bolts

Thank you.

The first dimension is 7.85"

The second is 3.36" but the two surfaces are not perpendicular (see pic). The straight edge is hard to see in the pic, it is laying flat on the bottom transmission mount surface and then the square is resting on that. When the whole thing is assembled, transmission, adapter and transfer case, it gives a slight upward slant towards the engine BUT leaves the trans mount point parallel to the frame rails. I have the adapter because.....I installed an NV4500 earlier this year. Round NP205 TO NV4500.
