Been able to spend a bit more time on the A this week.
Rear corner is now all sorted.
Next to do was have a look at the d/s front inner wing, blasting had showen up poor metal work.
and I even found a big crack in the chassie rail, this was around the area were I had cut the rail to mount the brake servo. As I am now having a remote servo, I can repair this section back to original.
(Please excuse the **** welding that was done 13 years ago when I was a novice

)
Right now it was time for a herble cigge and a cup of tea, while I deceided how I was going to takle the job. After some hunting around I found a section of inner wing I had cut off that very rusty yellow Manta before it went to the scrapyard. As luck would have it, it was just big enough to replace all the small patches in one go.
So the job I thourght would only be small has turned a bit bigger.
Having cut out the old wing, this gave me better access to repair and strenghen the chassie rail and repalce a section of the top rail.
You know how jobs just get bigger and bigger, well while repairing the rail I deceied that it would also be easyer to repair the bolk head while the wing was removed, so I have started to cut the bad metal out ready for a new section to go in.
