Have made what appear to be decent part F442 out of the hefty 2 inch by 2.5 angle but how to get the 5 degree bend in the thing is not at all clear. Tried bending in the vice but unable. How is this accomplished?

I had a heck of a time bending mine also, as I recall, I clamped one leg in my big vise and used a big pry bar between the other leg and the vise to bend it.

Same here

I used a thick piece of steel angle instead of the pry bar as this distributed the load on aluminum angle over a greater area …..welded a long piece of round bar stock on it for leverage but same idea

no plans around, what is the F-442? Should remember how I bent it... if I remember what part it was

I laid it on a piece of round 4130 and put it in a press.

These are the big aluminum angle brackets that the two center engine mount attach points are bolted to behind the firewall.
