There are two profiles for the door frames. My 110's split doors have the same profile as series rigs. At some point rover changed the profile used in the door frames. Confirm your profile before ordering repair channels. I stripped all of my doors, blasted them and then welded in repair channels, then had them galvanized. The door frame material is pretty thin, but a competent welder should have no problems.
