Aluminum knuckles for Kyosho buggy: which company?

[kulangflow]

Question for y'all:

I need to replace a front knuckle on my Kyosho Kanai 3 buggy. I am not familiar with the manufacturers for the few options I found, so I'm hoping someone can point me towards the best bet.

Kyosho?

Second question: Do you think this truggy conversion kit is worth the money?

Thanks in advance for any and all advice!
