Klaus et al,

Thanks for the answers and guidance. I will go ahead and complete the removal.

FYI, there was one screw-on fastener (not mentioned in the service manual) that needs to be taken off to complete the removal of the panel.

Any thoughts on the insulating wrapper (I mentioned on last picture)?

Wondering how messy the rest of the removal will be .....

One thing for sure - the three Allen bolts holding down the manifold plate are a bear to remove due, I believe, to the locktite used (red in color).

Have to pause here for today due to rain showers (no garage)
