Hi. I think you might have a couple of bent shock shafts there, either that, or some faulty original parts on the buggy when you bought it!, I've had my Bx for 18 months, and have only suffered with 1 shaft bent in a crash, the rest still have their original seals, so i can't fault the LRP items. Not wanting to be patronising; when you get your new seals, disassemble your shocks completely and roll the shafts across a piece of clean straight glass. Watch for them lifting away in the middle of the shaft?.
As for the Knuckles Mal, i order them direct from 3Racing in Hong Kong:
http://www.3racing.hk/main.php . or Stellar models HK might stock them on Ebay mate. be sure to search for version 2 though. And enjoy your blast mate, but make sure you loosen the servo saver off, and put some thread lock on the grub screw in the slipper to propshaft drive cup. Because i've had no end of retirements from my 6.5 turn brushless shaking the transmission to bits during a 5 minute race, so much so, that i down-graded to my 7.5 speed passion, which runs much smoother.
