Finished removing the last of the 1/4 panel edges & removed the inner arch.
This shows the full extent of the corrosion to the inner wing. For what I can see water has been getting in an additional hole left from changing a sun roof and water has run down the inner roof rail and found its way down the inner wing.
I have cut the lower part of the roof off where it joins the 1/4 panel. Mainly because I cannot get in there to split the joint and also because it is corroded so I might as well make a new one. It will probably be neater & I know the rust will be gone.
The wheel house looks to be ok as this is made of thicker metal and has more paint protection than the inside of the other panels which probably left factory in bare metal.
We must understand these were a very cheap vehicle sold in their masses to get the Italians back up and running after the war. They did not make these things to last this long, only to be reliable. So anti corrosion processes weren't that great, a bit like our own vehicles of the time. Also they did use poor quality metals, unlike what is used today.
The good news is I think I can make one using part of the old 1/4 panel that has similar shaping. I have sent e-mails to every company I can think of to see if they have a shell being scrapped where I could salvage this part from, so I shall hold on for now - plenty of other stuff to do.
Offered the new 1/4 up, not bad fit. Just needed some dressing up near the joints as the contours did not quite line up with the original. Once happy with the gaps I cut through the 1/4 panel & the underlying panels to get the best joints I can.
Then removed the small sections cut off the old panels & new sill and clamped the 1/4 in place then secured it with a few self tappers.
Next the A post. Gave it a bit of a clean up, the light surface rust cleaned up quite nicely. Decided to cut some of the lower section off as it was heavily corroded. This part needs to be strong otherwise the door will creak or even drop if it is weak.
Removed the outer sill, cleaned all the joining edges.
Beware these panels do not have electrolytic paint, why I don't know? Manufactures usually supply panels with this paint on them and it allows you to spot weld through it. Instead I have had to clean the paint off then spray the welded surfaces with zinc weld through primer.
Placed the sill back in its place using the self tapper screws, went straight back in its original place. rehung the door to make sure the gaps were ok then mig welded the front section to the A post, welded in a new section, then spot welded along the top of the sill to join it to the inner section.
Franko now has his inner & outer sills and a solid A post holding the door in the correct position. Its looking a whole lot better than the other side.
