We have been playing with different tcase/trans mounts as they move the engine back and forth in the engine bay.
The lt77 mounts had the engine too close for comfort to the footwells on either side. Using r380 mounts move it forward appx 2 inches. This position has it so close that I'm working on a block side mount to match up on the 4 cyl frame mounts so that a diy install will not require any welding.
Moving it forward necessitated the use of r380 floors and tunnel, and our adapter as the transfercase linkage fouls on the seatbox, but still utilizes OEM components and allows the use of commercially available carpets and mats. I think utilizing the Exmoor/Wright sound matting is prudent behind a Cummins.

This engine position has the integral oil cooler well behind the steering box on a lhd truck. Currently working with a lhd 90.

Very happy with the modifications we made to the radiators and intercoolers. In order to maximize surface/core area, our design requires removal of the pre td5 mounts on the front crossmember of the frame and drilling the frame for the mounting grommet as was done on the td5 and tdci trucks. Once the mounts are removed and crossmember drilled the original radiator mount grommets are used in the chassis to mount the radiator. The radiator and intercooler bolt together as an integrated unit as was done on the td5's.
This enabled us to use stock td5 intercooler upper mounts that all the trucks are already set up to receive with no modification. Mounting is rock solid & is not reliant on the slam panel.

A/C will require the td5 style bump out grill surround to accomodate the condensor and fans.
