Arctic Trucks remove the whole front end and replace it with Dana axles and all modified parts , the body is cut and custom arch are fabricated . I contacted them a few years ago , they don't actually sell vehicles only modify them but they were kind enough to source me a 6 year old Nissan Nivara with 38 inch wheels that they had modified for a customer . I can't remember exactly but it had about 90k on the clock and when i worked out the currency exchange rate the price was around £19000 for the truck . Then it would have to be shipped and import duties added .
I politely declined !
