I've cleaned up the area today, and will see what happens. One question (as a relatively new D2 owner):
What is the easiest way to remove the main undershield?
The only time I had to remove it is when I did the oil pump bolt but IIRC, the front prop shaft stayed in place. You will need to lift the vehicle from the chassis to extend the clearance between the undershield and the front axle and most likely, you will also need to remove the cross member.
