yeah i know wot ur saying..the reason i sed wot i did was because he asked wot a mechanism looked like for his sierra..u could have showed him a pic of a same style mech ie transit..this wouldnt really help him to fit a rear sierra mech due to points etc...as he seems to have limited knowledge on the subject thought best not to confuse....anyway.. where abouts u from? do u work for some1? interested to see if every1s as quiet as we are..
