Triumph TR4-250 Door Repairs
To allow the door to be repaired, some additional original sub assembly components of the door assembly have been made available. The two most common repairs are to the door skin and/or bottom frame because of rust and the door check strap bracket that has been torn or split in service. The replacement of the angled bracket for the check strap on models apart from early TR4s is quite a straightforward task. The spotwelds of the original item can be drilled out to release it and the replacement inserted. The new item can be attached with weld, as original. Those without welding facilities could attach the bracket with small nuts and bolts or even rivets after drilling to suit. The door frame assembly would be best repaired by cutting and welding and inserting a section as required.
Genuine original steel door skins are available to replace existing items as required. The door skins are made from zinc coated steel and are electrophoretically primed to give modern car corrosion resistance.
Do not forget that when you get to grips with your door other parts may need renewing or repairing like glass channels, private locks and hinges. These parts are also available to ease your restoration.
