Removed body parts still have collision?

I deleted all of my leg parts, (foot,leg,lower leg, etc) but they still have collision even though they are gone. is there anyway to fix this? Furthermore how would I go about removing limbs with scripts? How would I select a player without there ign? I've seen somthing about doing (Player) but that doesn't seem to be working...

Dont remove the body parts. Make them invisible and set CanCollide to false. For me it works
