I trimmed the front rh A pillar until I got to solid metal. It is in pretty good shape from here up. As you can see from the pictures I have made my first piece. It still has to be scribed trimmed and welded. I will not trim the bottom to length until it is welded in. That way I can know it will fit after I make the piece it joins. Also, larger pieces will not get as hot and when you are welding so difficult angles it will not blow through quite as easily.
I also ordered a set of outer rockers today. They are not too expensive and it will help me to position the inner rockers in the right space. I started another post concerning the odd way GM built the rockers but did not get any replies.
