*** UPDATE ***
Hi All,
Been awhile since I've been on here. Here is the progress so far:
1. Wheel Base has been shortened on the donor frame, by 3 inches (moved the rear-end and spring mounts forward.
2. Old motor/trans removed from donor frame.
3. Installed the EZ-Chassis frame kit to the donor frame.
4. Removed the front-clip from the Suburban.
Next on the list is unbolting the body for the move to the other frame... If all go well I might get to drive it again before winter.... I have added updated pictures to "My57Suburban" link.
