varieze engine engine mounting studs reinforcement ?

[Ratdog]

I know some Varieze owners have added reinforcement to the existing aluminum angles coming out of the firewall for the engine mount from the original plans .  Is there any 

info in the canard pushers on how to make this modification.  I cant find anything .  Im at the point in refurbishing this Varieze of putting the engine mount on and the engine and wondering if I should reinforce the mounting studs .

If the Vari is like an EZ, I have read where the bolts for the engine mount extrusions can be located and driven out and the extrusions swapped for something more hefty.  Some people have used steel angles, some used 1/4" aluminum angles, some have doubled-up 1/8" aluminum angles.  Pic from the EZ plans below.  It doesn't sound very hard to do.

It seems 1/8 inch 4130 angle is hard to find. My plan is to use square tube and cut it kitty corner on the Bridgeport to make the angle stock.
