I need a peek insulator that will fit a dead rabbit v3

Yea, so I was cleaning my attys and I lost the peek insulator that goes around the 510 pin on my dead rabbit v3. Rendering it basically functionless. Why couldn’t it been a screw or why can’t they give replacements lol. If anyone has one from and old atty or something that will fit. I would gladly pay you a few dollars and shipping. Or if anyone knows where I could procure such and item please let me know! Thanks
