Folks, it's two clamps and two or four nuts as I remember.  I'm a clutz who
didn't know how to change the oil when I got my first car.  I can do it, you
can to.  No one should be paying a mechanic to do this job.  I'll bet they
charged you more to bypass the thing than Ron would have for the new part.

Yes, they did!  They charged me $100.17.   I understand Ron has it for $70,
and since I am relatively close to the Bus Depot, I could pick it up - no
shipping $$.

Live and learn....
