DIY..as in custom? ooo, that's waaaayyyy over my head haha, it'd be worth more than the car is, theres a place in Bridport, that deals with stainless steel jobbies, I will call them up and get a price though.
I had thought about fitting myself, but i'm getting to soft in my old age, years ago in my teens, I was under cars no prob, but since getting married and becoming a dad, ive softened lol, would hate my daughters last memory of me, being crushed under a car...
