Did you receive the full size inner cowls? The gray ones? If so, I have a priceless tip which I will offer to you free of charge.
Buy the lower half panels which are in black primer. Many suppliers carry them. These half panels are formed correctly at the bottom, whereas the full panels ARE NOT EVEN CLOSE.
All you will need to do is cut the bottom portion of the full panel off and weld the black half panel to it. Trust me when I tell you that this tip will save you days of ridiculous metal forming labor.
Also, you will likely find that the two floor panels will be about 3/4" too short to cover the width of the original floor opening.
This is not a big deal. All you will need to do is make a small piece to fill the gap where the two floor panels meet at the seat riser.
This gap is located at the center of the transmission hole in the floor so it will be a very small piece to make and weld in.
