Can't do all that much right now on this as the panels won't be here until Wednesday.
I have now however repaired the upper sections of boxing panels on the A posts. I had already replaced the lower sections 3 years ago but the top sections weren't very accessible and the plan had always been to revisit this. With the bulkhead and dash rails out of the way, it was clear to see that they were in a pretty poor state.

Once I had cut the bad bit out, I made a card template

Transferred onto steel

And clamped to the car

And then welded into place

Then I repeated the same on the other side



I then remembered that I have a top dash rail in stock and as thats the first panel that needs to be fitted, I borrowed that and got it fitted.
Its not difficult to fit but needs to be in the correct place so best thing is to get it offered up

It should sit flush with the fold in the bottom of the windscreen boxing panel so I put a tack weld in the front edge both sides

The pics are a bit jumbled up between sides so I have used pictures from both sides to tell the story..
With both sides tacked, I need to get the height correct. The windscreen height measurement on most shells is around 410mm in the centre and each side above the outer screen vent screw hole so I added a copper backing plate behind this join

And check the measurement for this side

418mm....
With it clamped , I can now tap the dash rail up from where its clamped to get the desired measurement.
When I measured this car prior to cutting, the measurement was 412mm and another shell I have here is 410mm so I went for 411

Now I can weld that join up

And that holds the height correctly.
I did the same the other side and then ground flush

Then welded up the seam between the dash rail ends and the screen boxing panel

That needs shaping correctly with the die grinder but the bracing is in the way currently.
Last thing was to spot weld the end tabs to the A post boxing panel

And that is now in exactly the correct position with consistent 411mm measurements across.
Cheers
