looking for body mods/conversions for Duratrax buggies or st's.
Would like to find Sprint car or dirt mod body to fit on them.
Any ideas?

if you just mean that you want to fit a different - non-standard - body onto your buggy then simply measure the distancefrom the centre of the front wheel to the centre of the back wheel and the width between the 2 fronts and the 2 backs and then go to your LHS and start measuring shells till you find one that fits and you like the look of.
then it is just a case of fitting aftermarket body posts somewhere on your Buggy to mount the shell onto
