Minimoke8394 - Thanks, feels like a big step too !
Will_ - Thanks for the comment, as for welding practise makes perfect, just have a crack at it !
Update,
We got a load done today, pretty much finished the drivers side, I'll let the pictures talk !
Chopped out the rot from the arch -

Made a peice and welded that in -

View from the back -

Then the bracing came out -


Drilled the holes in the closing plate ready for plug welding -

Welded that in and trimmed the arch repair back to suit -

And then we fitted the inner sill stifferner -


Drilled the holes in the companion bin ready for plug welding and sprayed with Zinc primer -

Welded that in, will need some trimming back around the door step -


And then chopped out the rear quarter ready for the repair -

Applied top coat to places I can't reach when this repair goes in -

Held in place with inter grips -

Tacked in place, making sure to let the panel cool as we didn't want distortion -

Welded in fully and ground down -

Primer applied -

View from inside the companion bin (still needs the closing plate on the back welding in) -


Overall look -

Good speedy progress today, had some sunshine for a change so that made a huge difference. Looks like the rear quarter repair is off in the picture but it's not, I've made accurate measurements from two different minis and there the same, also I don't think the heelboards to blame either as again I took accurate measurements and have dry fitted the subframe a couple of times with no problems, I measured and re-measured and both sides matched up and was plumb straight so I think it's got something to do with the pattern floor I bought, but then again it lines up perfectly with the door step, which again is dead straight !
What a mouthful, but at the end of the day its 1000 times better than it was and won't be as noticeable when the outer sill goes on !
Anyway I've not got much left to do with this side now so will finish that and then start the other side within the next couple of weeks
