revo+3905 trans help

[mopar1994]

i just got a e-maxx 3905 trans for my brushless revo 3.3 and i need some help mounting it. ive looked at all the other threads that have pictures of 3905 transmissions mounted in revo's but im still not really sure what parts of the chassis need to be shaved off. i was going to make a bracket like jzemaxx did on his revo but i need to know what parts of the chassis need to be shaved down. pictures would be helpfull.
