1973 Dart swinger front clip conversion to 1970-1972 style

I just purchased an excellent one owner 1973 318 Dart swinger but I am not in love with the front nose clip styling. Any suggestions about converting the front nose on the 73 to the 70-72 style? what parts will I need, what parts on my 73 will be interchangeable etc... also looking for a great resource to buy NEW OEM, NOS or used good condition front clip parts, Fenders, hood, grill, bumper brackets, inner fender wells etc... basically a place where i can get the parts to swap out the front clip...

Thanks, Chad in Fort Worth Texas.
