355 tail light bulb holders

355 tail light bulb holders are not available as stand alone parts (only available with lens assy.) hence there are no part numbers in the parts catalog for them. the tail light assemblies are four different part numbers. are all four bulb holders different as well or universal? this is one of my right side units; not sure inner or outer. (i am in need of one left outer)
