Do these bumper trim pieces attach to the regular Bronco modular bumper or do they require Raptor endcaps? Also, would these fit my non-SAS Badlands without taking the crash bars off or do I need to take them off?
They need / use one of the bracket holes in the three tabs that are on the Braptor bumper ends…
If you get the Braptor end caps you still need something else, like this picture or fab a piece of AL
I purchased the ends to have different attachments for my extra lights, but if you just want the flaps, you can or have someone weld three tabs spaced specifically for the flaps.
edited here is a picture the flap uses just the center tab that comes with the Braptor end caps
2 of the bolts go into the foglight housing and the middle bolt goes into the Braptor endcap. You need the Braptor endcap to bolt the foglight housing into if that was part of your plan. Otherwise you would need some sort of adapter like posted above to go into the Braptor endcap.
