Rear Inner-arch repair using front wing?
 

Started looking at the best way to fabricate something to repair my rear inner arch where it has perished.

I've got new outer arches to weld in but I'm concerned that the first couple of inches of the inner arch is completely gone, so I don't have anything to go off by way of a template and was wondering whether anyone has previously used the front wing to *******ize an inner arch??

It seems to fit the general shape?

You can certainly use the front wings to make the outer arch, transpose the front left wing to the right rear arch and same for the front right to left rear, tot sure about the inner arch though, think my inners were fabricated from scratch.
