Arch trimming 90 rear tub corners

Hi my 90 truckcab has the rear arches cut right out, ive noticed that you can get some finishing plates that pop rivet to the tub and curve under to meet the x-member ive googled endlessly but cant find these anywhere.

Has anyone come across these before and know where I can get some from, im sure I saw them advertised a few months ago in LRO but cant find the issue.
This nice motor has them fitted which I saw on ebay

There was a bloke selling them on ebay a little while back. I was going to get a set but was put off by the £50 price tag. In the end I opted to make some out of thick steel which i welded and braced to the cross member. They were strong enough to jack off and easily protected the rear corners.

You can also buy a similar thing to my ones from 4 muddy feet which just bolt on.

Finished them off with a little strip of chequer plate butchered from some old rear corners (not fitted in pic)
