Help working on 73 duster doors. How do you remove the inner crash bar??

well i am slowly getting the body work done on my 72/73 duster race car. I have a 73 duster that i am putting the front-end off of my 72 parts car on. Well my 72 duster doors are no good, so just decided to reuse the 73 doors for now. so i was pulling the glass etc out of the doors and saw that these doors have the crash bars in them. I would like to remove them for less weight, so my question is has anybody done this? if so how hard was it to do and any tricks to get them out with out tearing up the doors? thanks Mopar65 :burnout::burnout:​
