Static Simulation - At least 2 bodies interfering

Hi, I am a student and for my final year project I need to model some golf clubs. I am looking to do a simple static simulation on them in solidworks.

I am having problems with creating a mesh, an error showing 2 bodies are interfering but are not showing up.

I am new to surface modelling and simulation so would appreciate any help with my modelling and simulation, I have attached the parts/assembly.
