Fibre-lyte can also make custom ones. I got them to make me a TRF419 style damper stays for my TRF414

Wild guess, but I believe they are there so you can add additional braces to increase the stiffness of the chassis. The holes lines up with the bottom holes and the TB05MS came out before the split suspension blocks.

That's quite interesting as back in 2020 I basically ordered an entire set of TXT-1 parts trees and other harder to find misc TXT-1 parts. Good luck to you! I checked my spares but I don't have any of the ones you are looking for

Have you tried contacting Borgfeldt (Tamiya) Canada? They should be able to order these spare parts (if it's still in production) from Japan.

I have bought/used TRF tools, HUDY, Team Associated (AE) tools, and MIP tools. By far my favourite and the ones I kept were the MIP ones. They look uglier compared to the other brand but the fit was much better/tighter. As for JIS tools, I just bought the Tamiya ones.

is it the viper body?

Very sad news. All the best for you and your family

Where did you find the LF2200? I can't seem to find them anywhere ...

The updated arms are 2.6mm in diameter. If you look at the TA05v2 you can see the sizes. I'm not entirely sure what arms are from the TB EVO IV reversible arms but probably similar. Here's the TA05 reversible suspension arm kit. Note the 4 shafts below the wheel axle and they have a flatten spot. That's where the set screws from the C hub and the rear hub meet and holds the shafts in place instead of the older e-clips.

Would be interesting if they re-release a version of the TRF414

Do a search for Double Shoulder Pan Head bolt. If you need the exact measurement, I can probably get it for you too but I have to find some time to disassemble mine TXT-1

If you have an example, take it to the hardware store (the ones that specializes in fastner) and see if they know what type is it then you can probably find it more readily. The only thing that comes in mind is a special type of shoulder bolt but this particular one has two pivot point.

I guess you can let me know who would be interested in buying it

It's about 10"
