IRS Circlip source needed

[ironman16nc]

I'm assembling an IRS on a MKII Roadster and am in need of two circlips used to hold the axle shaft onto the tri-lobe bearing and the outer CV. The Ford '97 Thunderbird part numbers are E9SZ-4K184-B and E9SZ-4K237-B. Auto parts say its a Ford supplied part and Ford says they are discontinued. I've done web searching with no luck. Does anyone know where I can get these? I need two of each. See pic.

They are hard to come by. I got mine from Mike Forte. You can also (usually) get them from Disc Brakes R Us.

Thanks all! Mike Forte was able to get his hands on the outer clips for me. I'm still trying to source the inner (thick) clips.
