What are these motor mount brackets?
Does anybody have a picture?
Doc Custer, do you have a picture you can take and
upload?

Attached are the pictures. Taken from inside the fuse. The firewall measures
0.17 and is stainless. The four corner mount brackets are steel, are powder
coated white and measure 0.070. Between the firewall and the brackets is a
0.125 Al spacer. The stiffeners around the perimeter are 0.125 x 0.125 Al
and run under the brackets, hence the need for the spacer. The brackets have
a doubler welded where the bolt passes through the firewall. It is about
1.025 x 1.125 in. All the pieces are riveted together with AN426AD4 rivets
to preserve a flat mounting space on the engine side of  the firewall.

The two bottom mount points have 0.180 Al angle with the various stiffeners
running under with spacers to fill the voids. The various pieces are riveted
together in the same manner as the corner mount points.

All Al angle is primed with a two part primer (crap green).

Doc

Thanks Doc.
OK so what I am seeing here is the inside drawing of the firewall?
Last attachment. Is that correct?

Darn, I mounted the engine on the wrong side of the firewall :)

OK no problem I will move the engine to the other side
of the firewall :)

The last jpg is the note I missed on the drawing.
Of course it was the rear view drawing of the firewall. Duh how
dumb of me :)

Thanks doc for clearing that up.

Yup. Aft side of firewall.

I omitted the leg dimensions of the Al angle stiffeners. They are 0.75 X
0.75 with 0.125 web thickness. I assumed you were most concerned with the
thickness of the material.

I thought the engine drawing showing the aft features of the (transparent)
firewall was useful and interesting.

The note says it is 3/8 scale. But when I tried scaleing off the drawing it
was off alot. So it should say **approximately** 3/8 scale. Just a heads up.

Doc

OK Doc thanks for the heads up. I have several sources for the dimensions.
Your sketch, this firewall dwg and the motor mount dwg.
I'll try to cross check everything.
