Oil filter adapter

I know my aluminum one will fit LA's for sure since it is over 30 years old and sitting in my cupboard all that time. I have cast-iron in '73 Challenger due to use of early HP manifolds for few years. Now back to OEM ('73) pieces but 'clearance' issues with custom exhaust would not allow the simple 'plate' (such as with 318's) as filter (even PH43) would hit pipe and 'dimpling' side (of filter) too rednecky.
