Daveinet came up with an excellent idea for making a front hatch cover for an RL24. Many of these have been lost over the years, especially when trailering.
For the front hatch cover, I would suggest buying a sheet of 1/4 plexiglass and then bending it.
You can heat it with a paint stripper gun. Sandwich one end between tow pieces of wood.
Heat up where you want it to bend and then use another piece of wood to push down on it and bend it.
If you get it wrong, you can always reheat is and correct it. I've bent many complex shapes this way and have found it very easy to get what I wanted.
I would probably try to find a tinted piece for style and reduced sun intrusion. You will probably like having a window you can see through facing forward anyway.
