Thanks again for all the wise advise that comes from this forum.
We successfully installed the Rokmen High Clearance Belly Pan, Rokmen Engine/Transmission Skid Plate, Tom Woods Double Cardan Driveshaft and
Savvy transfer case cable shifter.

Everything fit together quite well and it performs very nicely.
