Door lock cylinder, eccertric wont fit nicely into door handle Options

[Tking327]

i bought a new door handle and new lock cylinder from auto atlanta. The lock cylinder is porsche w german on the package insert. The handle i guess is after market knock off. This should not be hard, but i cant get the 'eccentric' (the cylindrical lever with a protrusion that is responsible for the unlocking function) to fit smoothly into the receptacle on the door handle. The fit seems too tight and i cant get the small square male and female alignments to mesh/lock in so that the countersunk head screw can engage and hold everything together. Any ideas? Why is the fit tight? It would make turning the key difficult

Thanks! Tom King, Denver

Thank you guys! Well, my old handles are beat up and missing pieces but instead of re-chroming approach maybe i could sand down the eccentrics that came with the new german lock cylinders a tad to be able to use them with the knock off handles. The fit it close just a hair too tight

short of that, where else might i buy handles and lock cylinders that will definitely fit together?
