Install is pretty self explanatory so I'll just mention the parts required and give some pointers as to the particularities of each option.
The front ends of all available Toyobaru models can be completely interchanged. However, more than just the bumper is required.
Below, I'll give you an overview of the basic idea behind interchangeability, some specific things you need to watch out for when doing this mod and then the parts list as far as I have it.
Also, since most will be interested in the Facelift bumpers I did not include the Preface part lists.
As usual I'm not liable if anything gets broken or goes wrong or is not road law compliant in your country.
