Thanks for the helps / views. I will drill it out and have a look at getting someone to fabricate it. Also need a new mounting stud as that snapped trying to undo it!

Hi guys, I’m new to Landy ownership and have just start work on a project 90. I have removed rear interior trim to discover corrosion in LH rear tub corner where it connects to side panel. Long story short cappings on tub look ok but I can’t find the name or replacement part for the corner...
