Hello,

NCL PWD means the person belongs to non creamy layer in OBC category with physical disability.

CRL PWD means the person have physical disability in general category.

Now come to your point, you said that you are already got seat in basis of NCL PWD rank. So you have must your NCL PWD certificate. Because when you go for the CRL PWD rank it will creating problem for you. Because it's a rank basis of general category and you have already selected for OBC category.

If you go for CRL category then your seat will be gone and you have to wait for your general rank.

I suggest you that just go for NCL PWD already got seat. You can contact the college for your problem also.

I'll provide you the college link below
