55.2-59 Ol' Blue

[8man]

Ok, I'm not sure what this part is called, it is the radiator support I think. Anyway, the truck had dealer installed AC in 1955, and it appears they cut and bent some of the louvers out of the way, removed the "X" cross bracing and took off the two little horseshoe shaped pieces on the upper corners when doing it.

Here is the louver removal after I've cleaned it up a little.

Then I shaped a louvre and welded it to a piece of flat sheet metal.

And, here it is all welded up.

Now for the real questions.
1. What is this piece called?
2. Is the "X" necessary?
3. Are the two straps on either side necessary?
Here is a picture of an old rusty one a buddy gave me so if I need the parts.

I could use the old rusty one, but it needs some rust repair on the structural supports and there is a bolt broken off that is very difficult to get to.
