Rog,
I glued one front spring assembly in place, then drew a center line on the frame down through the center of the axle mount. I then cut the spring loose from the shackles, cut about an 1/8 of an inch out of the shackles and glued the spring assembly back onto the shackles. Rinse and repeat for the other side. Did a similar process on the rear.
Not as low as I would like, and not an accurate representation of actually lowering a truck. Just a simple way of achieving the look, and as they say, "baby steps".
The engine is now installed. For some reason the camera is not catching the difference in color from the frame, but it is.
So no sleeper. I do want it to appear lowered, and that will help.
