A Home Depot Millworks Dept. fellow told be I can install a 32 inch exterior fiberglass door even though I have an existing 30 inch by removing a jack stud or king stud (forgot what the name is) on one side to make more room. Is that ok? If so, the hinge side is kinda close to the wall that is 90* to the exterior wall where the door is. Can I remove the on on the non-hinge side as I have more wall to deal with? Thanks.
