18 In order to properly "adjust" the Shaker's under-structure, use 2x4 blocks to raise the piece off the floor, and then use a small hammer or mallet and a block of wood to "adjust" the areas that need it (usually around the bends or radiuses). | 
19 After adjusting the Shaker's under-structure, reinstall the brace with your sheetmetal screws and see if the gap is closed. If so, it can be clamped around the flange ring. | 
20 Once again, clamp the Shaker's under-structure in place with vise grips and use sheetmetal screws to help keep it snugly in place. |
21 To fill in the gap around the ring and the topside of the hood, we used lead to fill the seam before we weld the under-structure in place. This will allow the metal to move around. Most folks would use another type of filler and that's ok. | 
22 Use a foam-type glue under the hood's bracing to eliminate the oil-can effect in the hood skin. | 
23 Before you install the Shaker under-structure for the last time, seam seal around the flange ring and clean the areas that need to be spot-welded. Also, apply adhesive foam to the parts of the brace that are closest to the hood skin. |
24 Before the Shaker's outside ring can be installed, you will need to smooth the rough castings on it. A skim coat of body filler works well for this. | 
25 After the brace is reinstalled for the last time with the screws, put the trim ring on to check the gaps once again. | 
26 Now spot-weld the Shaker's under-structure where it touches the flange ring and plug-weld everywhere else. Make sure to cool the welds, and keep them spaced far enough apart to keep the hood from distorting. |
27 After the welding is complete, the hood may need some minor bodywork. Remember, you just cut a large hole in the hood, so a small amount of body filler may be required. | 
28 After the rough bodywork is done, spray the hood with epoxy primer, lightly scuff it, and then spray it with a high-build primer. Don't forget about the underside where the plug-welds are. | 
29 Once you have the fillers smoothed to a perfect end, it's time for paint. As you can see by looking across the hood, it's impossible to tell it was originally a flat hood. |
