which is best way in my opinion ,you could use off donor if possible front prop ,rad and cooler frame pipes water and air,etc gearbox cross member, pas pipes ,front down pipe ,chassis mounts for engine,need to get 300 tunnel floor plates etc ,rear prop air box pipe and bracket allthough you could mod one, and rear exhaust system , the only welding is engine mounts every thing else is std bolt up and on, except crossmember needs chassis mounts for seat box grinding back abit rad frame needs bottom dowels fastening straight to frame and not bracket as disco ,side brackets grinding off ,gear box changing to def spec with old gearbox top and new selector rail and quadrant something i could do or advise you on
