On the mk2 the 4 bolts that secure the bumper are also securing the front cross member therefore the front engine mount . There are 2x8mm bolts that still secure it when you remove the bumper but I personally wouldn't risk driving it like that . The only way you could is to remove the 2 bumper brackets from the main bumper and refit them so that can refit the 4 bolts .But make sure there are no jagged edges exposed and that you have all your indicators and numberplate as Mr Plod may not be too happy if you get stopped.
so is my caddy legal and safe ?,its a mk1 caddy that has been debumpered on the front ,do i have to have a bumper ? and is the bolt situation the same on the mk1?
