Hey man, yeah the 9th gen is waaaaaaay different so that would really be something to fit it! But given your year and location, I figured you meant 8th gen.
Cool, you found my page. But I don't use that bumper anymore because I wanted more of a stock look.
OK, so now you have the bumper. What is your goal, you don't like how I did it, how so? How would you do it differently? I know of some pics that I could find.
Also, I will be glad to offer further explanation on anything that confused you
As for side skirts, you can fit any side skirts from 7th or 8th gen rolla. They are the same. There are plenty of 7th gen side skirts. I have 3 sets of side skirts lol. The first were made my Erebuni, and I got them on discount clearance on Ebay because they were discontinued. Good luck finding them. Then, I got the usual side skirts you see most people with... but I did not use them. Now, I have JDM side skirts, OEM Toyota from Japan. These are great!
So yeah, I am here to help
