Hello all, I was wondering what it would take to convert my xxx-cr buggy to a xxxt-cr losi truck parts wise? What parts do the buggy and truck have in common? Also roughly, how much would this cost or would it be easier to get a used truck? Thanks for all replies.

Buy a truck. There is only a handfull of parts that the buggy and truck shares.

Go to www.losi.com
You can download both th XXX CR and the XXXT CR parts explosion.
You can compare part numbers and get a rough idea of cost. Then you will agree with Chill Will. Plus you will have two rides!!
