Help on Extending a bit chassis

Any tips? I may extend my microsizer chassis to fit my now departed zipzap's mustang body. Will I run into ANY problems with wires? Do I need to extend any wires (In that case I woun't do it) If I simply cut off the front end & extend it out with tape & plastic will the steering wires be long enough. Don't tell me to "do a search" cause I don't see a search feature on this fourm. Thanks *~SBR~*
