there is not much out there that ive found and ive looked since i bought mine new. this bumper was marked toyota, and i made some brackets to mount it as well as some alum diamond plate to cover the top to make it look right. if you see a vehicle with a bumper you like, measure the width and you might be able to modify it or have it modified
That's the website I found for roll bars. It advertises them as "made to order" so i can only assume that when you go to order it, they'll make it to your specs. if you find anything out about grille guards or anything like that, lemme know
