there are many differences between the four cylider and six cylinder models for the street there is no way to convert a four to a six they have a completely different front end they have different diff mount locations different hand brake mounts etc etc the interiors are the same the doors and windows are the same the boot lid is the same but thats about it.i have seen some very tuff four cylider models with small blocks in the engine plated with new tunnel front floor and tubs! they are gold to wreck for people doing up six cylinder lj lcs though hope this helps good luck!
