How bad is that rust? - Rusty trailing arm

[kingcrunch]

Hi,

for my project i aquired a set of trailing arms that looked good on the outside but had some rust trapped between the C-channel pieces.

I straightened them, split them and had them media blasted. The damage is like 0.07" in the deep spots, which is halfway through.

I planned to use more plug welds and plate them like C20 arms (plate running 2/3 of the arm on the underside and 1/3 on the topside).


To abide local law i would really have to stick with stock arms for what i want to build.
NOS arms seem to be hard to come by (but i would buy these no matter what they cost if there were any available).


Speaking of replacement parts, does anyone have experience with the repop arms LMC sells?
