The right rear baffle is fitted in place. There is a pre drilled hole in
the baffle to clear the engine mounting bolt (see arrow in picture):

Some trimming was needed to get the baffle to properly fit the engine.
Just a little around the area toward the top and near the engine bolt
hole. It was also trimmed a bit down on the side of the engine area.
Here is the right rear baffle, showing how it meets up with the center brace
that we installed earlier:

I might have to remake or re-shape the brace. Just eyeballing it, it appears
to be sitting a bit too tall to fit under the cowling after trimming. We
will see when we start trimming.
There is a little brace included with the kit that fits a threaded hole on
the side of the engine case and gets riveted to the bottom of the right rear
baffle as shown here:

Note that the oil fill tube had to be removed and the hole was covered
with some tape to keep debris out of the sump.
The right rear baffle was then drilled and clecoed to the side baffle using
the pre-punched holes:
Next the first of the two left side rear baffles was trimmed a bit to fit
and installed:

This inner one just slips in place and overlaps the right one at the center
brace support.
The inner one has an odd shaped hole to clear the engine mount. It
kind of straddles the mount as shown here:

I'll later fill the gap around the engine mount with some of the baffle
seal material.
The final rear baffle is the outboard left one. It also has one of those
little rod/bolt combinations that slide into a slot in the cylinder head
(like on the right side):
Van's made this baffle piece (and the side one that it connects to) out
of some thicker aluminum in anticipation that an oil cooler will be mounted
here.
