rebel body kit,few questions!

[STINKY NINJA]

Are genuine rebel body kits ford stamped or were they outsourced and have other manufacturers markings?
Ive seen lately rebel rear bumpers which are all yellow on the inside,one ive seen for sale on gumtree,one is fitted to my s3 220 and the one fitted to a red rebel i looked at today,all yellow on the inside.
Id like to know if my rear bumper and skirts are genuine, and if there are markings where are they so i can check?
Mine has stainless mesh screwed to the bumper just like the genuine one i saw today,almost like the grill on a te50.
Can anyone with a rebel confirm this for me please.
Cheers
