I may be late to this thread, but in 1999 I purchased a whole bed from Mack Products in Moberly Missouri. I'm not that far from them and drove over and picked up the whole kit, save a bunch on shipping. I was really pleased with the whole setup, having never worked on an old truck before this or having anything to compare it to, it all seemed good to me. Panels were straight, corners fit right, wood was good quality, it was even package well.
I don't think you could go wrong with a purchase from them, pretty sure it was all made right there.
