Retrofit 5.2 in a dart: oil pan

Hey I have a very annoying problem. the magnum 5.2 engine that we put in my 75 dart has a rear sump oil pan and my steering will only allow for a front sump. after trying out the oil pan from the original 318 it became obvious that its not a simple bolt on replacement. long story short i need an oil pan for a 5.2 magnum engine that has a front sump, and if anyone knows where i can get one it would be GREATLY appreciated. thanks!
