Should have done it while the headers were out makes life a helluva lot easier!!!

 

Update
The motor mounts were NOT the issue.

After replacing both motor mounts and transmission mount... here's the header "clearance" i had at both driver and passenger side frame rails...

Passenger:


Driver:


Y pipe at 4x4 driveshaft:


Picture of new Passenger side motor mount:



The mounts did absolutely nothing in terms of gaining clearance. It's clear that the 1-7/8" Speed Engineering headers themselves are the issue. Terrible fitment.

I ended up denting the headers up for clearance.

The transission mount gained me maybe 1/8" of additional clearance of the 4x4 shaft and y-pipe.
