I was looking at the dogbone when I saw the hex's. This would be handy for the guy's doing muggy5b builds. They only seem to be available from hpi-europe. Of course, I don't know exactly if they will fit a truggy but these look different to the ones avaliable elsewhere - http://www.hpiracing.com/products/en/102530/

Has anyone got these?

Looking closely at it, they might need a liitle modding
