The car uses a stag radiator (with fan shroud as fitted to certain export USA Stags), these don't mount like a standard 2000 radiator ( 4 fixings into the vertical radiator panel) but have 2 bolts on their lower face which mount on to a horizontal panel, with the upper 2 mounts on the vertical top surface of the radiator.
So we find that triumph used a stag lower radiator mount, with the ends made flat, and bent in to a U shape welded to the chassis rails, and tacked to the back of the radiator support panel.
What remains of the lower mount is shown here
Please note in the top left of this picture the crude cutting of the original radiator support - that diagonal line is where it was cut
This is important as I need this to reference the rest of the front end repairs. I can now remove and replace, battery box, radiator panel, front valence etc, using the headlamp panel as the fixed front reference point for distance, working backwards towards the engine.
