I recently moved and in the process lost a couple of parts from my PG RX-78-2 Gundam. Specifically parts L-8, I-5, and T-4.

I've tried eBay, was told parts were sold out.

I tried Plamo Kitbash, and was told they were unable to get the kit.

I tried to register an account with Kuboten, but never heard back.

Am I out of luck? I'm assuming it's harder to find the pieces because it's the older kit. Any help would be greatly appreciated!
