Replacement parts for HP Latex 310 2" to 3" core adapter and spindle cap

Where can I find replacement parts for the 3" core adapter and spindle caps for the Latex 310? I don't need the entire spindle rod, and I can't find anything online for the 310. Any help would be greatly appreciated!

I dropped my caps and cracked it, I spoke to the company we purchased the printer from and they sent out replacements. If you didn't buy the printer from a certified company, you could try contacting any company which sells latex printers and ask if they can order you some from HP. Alternatively I have the spindle ends I broke they're not terrible if you want these ones.. (our is a 360) so I don't know if would fit

Thanks. I appreciate the offer, but I think the 360 is different. I ended up buying the 3" adapters for the DesignJet. They are a little bit smaller lengthwise and the fit was too tight on the core. So we sanded down the edges with a Dremel, and now they fit. I still can't find just the blue spindle cap though, but we are able to make this work for now.
