RH A-Post Base and Nearby
With the A-post base out of the way, the true condition of the inner wing was revealed. Also, some welded holes could be seen a bit further forward, so we elected to replace the whole area.
As Barry says: You can buy this panel, but I have the tooling here, so can make it out of full 18swg, which gives plenty of meat. Frankly most of the time is tweaking the fit to suit a particular car, and this would be the case with either my panel or a bought-in one. This way, I can tweak it as I make it.
End fit has ended up fine, and you can see what those MIG welded pin holes look like from inside. Definitely better off in the bin.
