It would be pretty easy to box the front tabs also, and would probably be a good idea for your project. The whole front subframe began with the 114 cars, in fact my '82 has a 114 subframe under it right now. I had thought I remembered the boxing of the rear lower control arm tabs on the '79 going right under the arms, but after looking under my two cars just now, I can see that it is like your photos. Not as strong as I remembered, but a huge step up from the old setup, which as someone said, they continued with through the '85 model year.
