I had the same rot as you do. I was able to replace just the upper cowl panel as my lower panel was good except for some pinholes which I welded up There are two pieces to the upper cowl. You definitely need the upper and you may be able to patch the lower if the rest of it is ok. You donít see it when youíre done but you need a sound surface to attach the upper cowl panel. Donít waste your time with the dash patch panel. Itís designed for a 70-72 chevelle and is double the thickness of your upper dash panel. I tried to use it but when you have rust like you do what is left of your upper dash panel is paper thin and is difficult to weld to a much thicker part without blowing holes in it. I bit the bullet and bought the replacement dash panel. Itís a much cleaner solution and fits well. I did have to adjust the lowerdash panel slightly but for a replacement part itís pretty good. If I were to do it again I would just buy the complete dash panel.
Thanks for the reply. I wasn't sure about this part of the panel selection and the vendors don't tell you how large the pieces are and what size they will repair...Just length.
Okay so upper cowl vent panel. Check thought so.
I'll look at the lower to make sure solid and I can weld patches to it as you said no one see's it and it needs to be solid.
The replacement dash panel...is it just the top part of the dash? I didn't think the dash was a two piece unit. But I see the top is separate from the lower part where the steering mounts and the glove box is housed.
A you tube video says it is screwed to gether...is this so?
I'd rather not go with the dash replacement dash panel...that is the whole thing correct?
May I ask where you got the panels from the upper cowl vent and the upper dash?
I attached the photos of the pieces and did find a pic with the thin panel in place but as you said they probably had thicker metal to weld to on the upper dash than I will have.
I do not have a picture of the dash repair panel just the thin one assuming there is a larger piece.
Thanks again for helping me out...
