Update on my fender problem. I looked at two other chevrolet trucks yesterday in effort to determine a course of action. Discovered I was headed in wrong direction. The left front shone in the pix in above post is the wrong curves. The right in the post above is the correct for my 48 chev truck. Discovered that the left front has been hit - or some other damage- and whoever did the repair - if one can call it "repair' did not get the curvature right.

So, now I have to peel off all that 25 plus year old bondo and the tack welded in patch and rebuild the curvature at the bottom of the fender.

Oh well. Two steps forward and one back. About right for restoration work.
