lokar kickdown linkage 727 question on 440

If your carburator is stock and doesn't have the bottom tab, you can use two 2" 90 degree angle braces from Home Depot. i doubled them up for extra strength, you can see them in the picture. as far as the throttle linkage on the transmission, i push back on the lever (there is usually quite a bit of free slack that does nothing ) until i just feel a light pressure starting and thats were i make my intial setting, which is usually real close, and will need very little tweaking
