Part Not Meshing Due To Interference

Greetings all,

Have been browsing these forums for a while now and they have helped me immensely. Certain little tricks and tips that I needed to continue with my design in SolidWorks I had found here with ease. This current problem I am having now, however, has been persisting for longer and I have not seen a topic that has pointed me in the correct direction as yet.

I am quite new to SolidWorks Simulation and as such may not be very use to its abilities and things of that nature. The part I have attached have been giving me problems during meshing due to interference. I am not even sure to check what is actually interfering, much less to solve it. I would appreciate any assistance I could get on this. Possibly a hint on if the way I constructed my part was not well thought out. It may have been as I was just drawing as I got dimension from a very old standing machine.

Please let me know a way to tackle this issue as soon as you get a chance to when you can. Thanks for all help in advance.
