Crack in engine mount gusset

[kmach]

Hi all,

while doing my annual I found a 5/8" crack in a gusset on the engine mount of my model 5 outback.

I believe this mount is made of 4130 chrome moly, can anyone confirm this.

I think this should be weldable with out removing the mount.

Any thoughts, tips appreciated. 20170914_211839.jpg
