Thanks Eric, I appreciate your honesty. There may come a point, when I have tried several times, that I give up on trying to fabricate the panel and use a scrapped floor as you suggest. But for now, I'll attempt to develop enough skill to construct the correct shape myself.

We'll see. And I shall keep this thread updated as I go.

It's kinda daft when I think about it - I've owned this car longer than I've owned any other, and yet I've never driven it! iIn fact, the only Beta I've ever driven was a 1.3 coupe that I test drove but lost out on 6 or 7 years ago!
Still, I have a welder, steel, and, can manufacture some time now and again, so I'll get there eventually. And when it is on the road, it will be all the sweeter knowing that I did my bit to resurrect it.

Cheers
Duncan
