Hi!!
You can get them at rainbowten.co.jp
The square parts for the TA04 by square are much better, the TBevo knuckle arms, and rear hub are the best aftermarket stuff you can get for your 04.
Get the 1.5 degree toe in hub for the tbevo3, and the knuckle arm!! They are the best!!!! And perfect fit! Plus you can choose from red, blue or ti color.
For the rear hub, they are more advantageous if you use it withhe tao4 alum hinge pin holders, so you can get a total of 2-3 degrees of toe in, I find 3 degrees of rear toe better!
Then, you can double ur upper deck, like what I did to make it stiffer!
you can lok at the square web site to see the products!! then use altavista world translate so you could undrstand what it says
Merry Christmas!!
