Thanks Kevin as usual a very good suggestion, I did end up going a different route though. Yes, it is an early subframe that’s actually in pretty darn good shape. Just needed a little attention here and there.
Almost but not quite finished with the subframe repair. I straightened up the frame horns earlier just before fitting the front bumper but still need to fix a couple of chewed-up bumper bracket holes (link). As I don’t want to possibly move the original mounting hole I decided to try and make a plug that replaced just the missing material.
