'86 VFR 750F Need front brake piston cap

I smashed a front brake piston cap on my '86 VFR 750F while using a bit too much air to free it. Anyone have a good cap and willing to part with it? I have a good piston. It would be a shame to replace the piston just to get the cap.
Thanks, Steve

 

Stephen, I have both calipers from my parts bike still. If you can give me a picture of the exact part you need I'm sure I have it. Or if you want the whole caliper I could ship that to you as well.

Here's the left one, I took these the other night for another member who needed a bolt:





I've also got the right one, just don't have any recent pictures of it.

 

Great! What I need is a good piston out of the caliper side you show in the first picture. The cap on the piston is really what I need. If you have trouble getting a piston out, what do you want for the caliper?

I attached a picture of what I need. It is the piston out of the caliper behind it.

 

I believe I have an old caliper I can send you as well. Let me know if you still need part.
