Finally was able to put some time in tonight. It's long overdue.

The rear differential is just about ready to install. I just need to decide if I want to do anything in the rear of the car, work wise, before I install it, as it takes up a fair amount of space.
Fun fact: The OEM front differential mount, used to mount underneath the diff and attach to the cross-member that holds the front of the lower control arms in place. This means that under acceleration, and the differential front begins to lift from torque, the mount would be in
tension. This resulted in excessive movement and clunking, that Nissan tried to quell with a "limiter strap" which was a rubber strap looped over the top of the diff, bolted to the underbody, that would attempt to prevent movement.
The setup I am now using, called the "Ron Tyler mount", utilizes a modified GM polyurethane mount that is instead top mounted, putting the mount in
compression under acceleration. This means zero clunk! The poly will mitigate any harshness/vibration, as opposed to a solid mount.
Also need to purchase slightly shorter bolts than what are pictured. They are excessive, I just wanted to see if everything would go together correctly.
