But I have tested the proposed location for the AV80R. It fits, and will look, great. Sorry, no pictures. I couldn't hold the unit with both hands and work the camera at the same time.
Work has started on replacing the baffle seals. As you can see from the above photo, the seals were well past the point of needing replacement. They appear to be the original seals. Which is too old by more than a few years.
This is the seal kit that I ordered from Aircraft Spruce. It appears to be good quality material and the price was very reasonable. The kit includes the seals, two packages of rivets (it looks like way more than enough), washers, and a package of screws and nuts that I haven't figured out yet. Note that they even include an appropriately sized drill bit.
I worked on removing the old seals last night. It is fussy work drilling out the old rivets and pulling the old staples (yes, the factory STAPLED some of the seals in place). I worked until the battery on the drill gave out. I got about 2/3's of the rivets out.
A good deal of care is in order as the baffles are very light gauge aluminum and can be easily damaged.
I also got educated on the differences between "old design" and "new design" drive couplings for the alternator. I purchased a new drive coupling from Quality Aircraft Accessories. Who are, by the way, great folks with which to work. Those little puppies are $574 each with a $500 core charge. The bad news is that the "old design" coupling is not an acceptable core. It turns out that if the old design coupling fails, it tends to spread bits and pieces throughout the engine. So having the new design is a good thing. But $1,074 for that small part is more than slightly painful.
