88-98 bag cups

does anyone know the measurements of the fullsize chevy bag cups (dual or single port)like the bag cups from SuicideDoors.COM. How tall are the uppers and lowers tubing from side welded to the circle plate, how tall is the pipe???

im building a set and just need to know how tall they come or the measurements of 88-98 bag cups "cut to lay out" as i've heard it before.

i make them 3 inches top and bottom and it will lay 0s as long as you have drop spindles

3" uppers and 2" lowwer lays 22" thats the size we sell
