I installed mine a few months ago as an "I need something to do during COVID times." Also nice to have that peace of mind. I didn't remove the turbo oil line when I did mine. Everything went really quickly and smooth with my Milwaukee 3/8" M12 ratchet. But I'll tell you, the topmost bolt was the killer. It turned what should've been a 30 min job to an almost 2 hour job. Having to turn a little L-shaped allen wrench less than a quarter turn at a time was brutal... But glad it did it! Haha!
I did the same process as @Hank how he did his.
I stumbled on his after I saw his page: Hank's RS - PTU Brace
After you torque the three bolts, you can "feel" the correct torque on the 4th.
Also note the washers orientation:

Great minds think alike.
