Yes it will be a bit of work removing and replacing it all
Wel I started the morning off finishing the cut away prosses. Then I bent up some inner rocker panels that have a nice return lip for the floor to sit on as well as a small return lip at the bottom to add a bit of rigdity to the rocker. Then it is a matter of clamping it all into place and test fitting it all. Once you are happy with the first round of fitting then I like to use self tapping sheet metal screws to hold it all in place while I test fit the door. Once that is to my liking I remove the door and unscrew it all, clean and paint all the parts with rust prevenative paint/ primer.
Time for lunch then weld away!
