P/N 4B3555 Need retainer clip for steering clutch throw out bearing on D2

Need wire internal retainer clip for the steering clutch throw out bearing for Cat D2.   Cat and General Gear in ID dont sell the retainer clip.  Does anyone know 
where to get a replacement or what type of clip to use for the steering clutch throw out bearing?    The D2 parts manual number is  4B3555.  Thank you for any help you can give!  Lou

FP Smith shows having some.

Look at the FP Smith. How would I search for it? Use the 4B3555 Caterpillar part number? Will keep looking at the FP Smith website. Thanks. Lou

I probably have extra if you can't find any elsewhere

Thank you for the offer. FP Smith did have 7 of those clip rings, Very much appreciate of your offer. Lou. Barber
