Wanted: Modern Feniex S-019 (S-600) parts needed

I am in the process of remounting an older six light head Feniex bar light on my new truck. The model is an S-019 which is a six head Feniex bar. The cable had been cut REALLY short so, I dismantled it and replaced the entire eight wire harness. All works well, however the end cap that has the strain relief promptly cracked in half and the small, black retainer clips that go between the light heads and lock them into the aluminum bar are very brittle (one broke) and are not flexible anymore and struggle to hold the heads in place. I emailed Feniex but wondered if anyone here has parts or can advise if they are still available. Bar works great and I would prefer reusing it rather than ordering an new one.

Thanks

Mike
