Thanks for the pics of the Mack, Somebody did a nice conversion on it.
I got a few more things done over the weekend, I cut the engine access and another area for storing chains and straps towards the end of the bed top. I also found a small mistake in the cab, it was 2mm shorter in length and highth on one side, so i had to do some cutting and refilling, glad this is plastic!!! Here are a couple new pics, Thanks for all the great comments, and thanks for looking,
Dave
