No you cannot use your box as it it. I'm guessing you have the mt75 box in ATM so u can modifie it to work. You need the bell housing and input shaft from an mt75 4x4 box. Or you can get a type9 v6 box. Is the engine boa or bob? As far as I'm aware bob is abit harder to sort the loom but not knowing a lot about wireing I'm not to sure but some one on hear will help you with that. I've just put a boa in my 3door so If you need any help let me know
