Both switches, the actual switch itself, are generic parts you can buy from MCM Electronics or Digikey. Problem is figuring out which one you want AND I think the divider switch is fastened to a bracket that you'd need to re-use. I think the swtich is riveted in place, so you'd need to drill the rivets out and replace the switch itself.

Here is where you can't use the SLK320 part, cause the '320 top is a retractable hard top. This is where the Crossfire IS NOT an SLK....

Give it a few days, guys, someone here will chime in with either a part or a source.
