I think the chassis is longer so not all parts are interchangable.I've been looking into getting the magnum parts to add to my mt2 and from what I've seen this is what you need

ff249 chassis 39.99
ff239 center drive shaft 18.00
mx002 gas tank 16.00
ff237 top brace 12.00
ff238 servo mounts 5.00
ff248 gas tank mounts 5.00
ff210 brake seat 5.60
-----------
101.59

All those prices are off http://www.horizonhobby.com/ Other than those parts I think everything else is the same. Except the engine of course.
