they arent commercially available any more... i had the same problem a while back...
i think dakitez had a good deal on the whole truck a while back... maybe give him a call and see if you can upgrade the whole thing?
they make a bionic upgrade kit, but i couldnt use mine due to the older kingpin somehow fusing wit the rest of the truck- jaws of life couldnt break
the bond... i can see if i still have it laying around... if i do, i can ship it to you cheaply, even include some yellow cubes if i still have
them... the new yellow cubes are much softer than the old ones, btw
