Steve's top motor mount is a better
version of what I did (mine's massive overkill), but we both can
make vertical adjustments (tilt). I could make very minor
horizontal adjustments with my top mount tubes, as well, but it
would load the bottom mounts asymmetrically.
I've attached pics of my alternator mounts (Renesis). Note that
these are 'in progress'. The alternators are Nippon Denso 55 amp
from mid-90s era Suzuki Samurai, etc with 15 mm diameter shaft.
(Difficult to find serpentine pulleys to fit 15 mm shafts; 17 mm
are far more common. The alternators from early 2000s era Suzuki
passenger cars look like they *might* be the small frame 15 mm
shaft with serpentine pulleys, but the mount ears are different
& won't fit where the stock Mazda alternator fits. If you're
running regular V-belts, it's easy to find V-pulleys for 15 mm
shafts.
The #2 alternator has a pulley from a power steering pump with 15
mm shaft. It will be run by the 2ndary pulley on the Renesis
e-shaft. Bigger drive pulley; bigger alt pulley.
Hope you can get some useful ideas from the above.

Small Alternator on Renesis.
In Glasair there is very little room above engine so
thermostat housing and alternator needed to be dropped.
Sorry the pictures don’t show mount.

The attached phto is of my
alternator mount and rear motor mount. It is
attached to the engine using 5 bolts where
various accessories were mounted in the
automotive use. The bracket is pretty simple,
and the link between the bracket and firewall
can be adjusted in length to change the vertical
tilt of the engine. I will send two more photos
(to avoid going over limit on size)
