I have been searching for guidance on how to remove the heat shields around the catalytic converters on a 1994 Series 80. Embarrassingly, I replace the clam shell around the Cats 5 years or so ago but have completely forgotten how to get the upper off after getting the lower separated. I thought it came out to the outside of the car once you had that heat shield out of the way.

I would appreciate help as I am getting around to doing the rear heater lines. Sadly, bypassing is not really an option in the family.

Thanks,
 
IIRC, they're just 8mm nuts that hold the uppers in place. I used a 1/4" setup with a uni-wiggle socket. I also used a Ritchie-ratchet to access the harder-to-reach ones.
