1972 Dart LS swap

Hi everyone🤗. I am a new member and so glad that I found you. A little about my project. I have owned this car since I was 9. Built it, drive it, wrecked it, started restoring it about 10 years ago. Got married to my childhood friend and adopted his son, and then we had 2 kids together. So now we are current.

I am restoring my 72 Dodge Dart swinger. But putting an LS engine and finding it difficult with the oil pan. Does anyone know where I can buy the oil pan to fit around the center link?
