I'm changing my 1990 from big bumper to metal. My Haynes manual doesn't cover big bumpers, do I need to source hangers etc? I'll be fitting a towbar later on, should I do it at that time? I've observed there are two different towbar fittings one for each style, but after downloading the instructions for both types and can't decifer if they include bumper brackets.
Help appreciated thank you, also can anyone tell me how to remove the door pods safely?
