The DOHC's front steel lifting strap is often used as a dogbone mount.
In my case, it broke the three-hole half-circular Power Steering pump
mounting area.  In order to make a stronger dogbone, but keep the ideal location
I had to figure out how to get a few bolts into the head, like the standard
Lumina DOHC dogbone mount does.  This picture shows the new dogbone mount
in place with the standard engine lifting strap bolt already in.  But... you
get the two other bolt holes shown--which go into the head--adding considerable
strength.

So:  where do these bolt holes into the head come from? they come from the timing belt
tensioner bracket, which is using those two holes. I got the dogbone to share these holes
with the bracket by millingoff a 3/16" flat surface on the back of the bracket, so the 3/16" thick
dogbone can fit behind this aluminum bracket, and both can use the same bolts.  The surface must
be exact, and should only be done using a mill.

Not pictured is a small amount of grinding I had to do the the back of the timing chain cover to clear
thisomewhat thick dogbone bracket. The steel lifting strap would just snake down into that crevice,
but I had to grind out a bit on back of the cover to make a thicker piece of steel sneak down in there.

So: here is the mount installed. the dogbone using the three lower bolts in the head
plus the upper one on the cam carrier for stiffness. I avoided using ANY holes
 on the power steering pump mount since it's flimsy. If the dogbone breaks, the worst that
can happen is it breaks the hole tapped into the cam carrier, which is not that big a deal,
when thinking of possible disasters. I suppose that one could worry about it breaking down low
and affecting valve timing, but other dogbone mounts integrate to motors in such a way that they
can cause similar disasters.

I also wanted to use the standard Iron Lumina dogbone mount next to cylinder 6.
This intuitively wants to be very close to the Fiero firewall. Seems great until you
notice the firewall is about 16 guage steel thick, and that's IT!!.  I made this engine
mount similar to what you can buy in any store, but with a properly sized donut in it.
Just sooooo happens, a cut apart Ultimate Dogbone from the Fiero Store is the
perfect fit. I cut the round portion off and welded it to a 1" tall mounting surface.

And lastly. That thin steel wall? Strengthened it with 1/8" thick plate spot-welded to help
prevent brittle breakage of the sheet metal. A bonus pic of my DOHC ECM sitting
(well.... hanging out) in the standard Fiero ECM place. It sits on a piece of foam and
though it's not bolted in per se, it's snug and safe when the center console peice is
put over it.
