takeuchi TB15 mini excavator

[u122423]

I bought a TB15 mini excavator to use around my house, so far I love it. I was wondering if anyone had a outlet for pins and bushings. I have a parts book with the takeuchi part numbers but I cant find them on the internet. I have spoke to the near by dealer and they seem ultra expensive for what they can get me. All I can get out of them on the size of the pins are 30MM. Any advice would be great.
