Engine tin back from powder coating

So, the engine tin is back and looking very good with a couple problems. One piece of tin is missing which is situated under the fuel pump. Also, it turns out that the car came with an incorrect (early) heater box. It will run with it, but unfortunately doesn't cool as well so I really should get another one. I also need to find some new J-pipes as the old ones are rusted through, and I feel like I'm forgetting one other important piece that's missing as well ... hopefully I'll remember soon.
