Are all Sidewinder rear bumpers the same/just different colors?

[RobX-1]

Need to replace the rear bumper in my buddies red/white '19 Sidewinder LTX SE but it appers the red bumper is no longer available for that model (SW1NLDKS):

BUMPER, REAR 1
8JP-K7541-60-00

The other color combo for the '19 SE (SW1NLDKS) has the rear bumper available but not sure what color it is as I can only find images of the '19 LTX SE being red/white unless the SW1NLDKS is for the LTX DX model which would be gray/back with what appears to be a gray bumper. Although I haven't found any used red rear bumpers, I have found other Sidewinder rear bumpers for sale but with different part numbers that would seem to reflect a completely different part rather than just a different color. For example, I found a white bumper (8KG-K7541-21-00) but not sure it will fit on his LTX.

Question: As long as it is a Sidewinder rear bumper and the color is acceptable, will it fit? I also wasn't sure if all Pro Cross chassis share the same bumper where I could expand my search to include Viper rear bumpers as well???

So, any year bumper for a sidewinder LTX is the same, gotta be careful with the Viper bumpers as most will work but I know 14,15 and 16 MY bumpers will be longer as they used a 141 tunnel on those MY.

Thanks, I think that clears up the difference in part numbers being due to the varying lengths of the bumper to match the tunnel (ie. SRX/LTX, XTX, BTX) and I will just need to ensure the bumper is for a Sidewinder LTX. If the red LTX bumper is no longer available, hopefully I can find one in either a white or black.
