[MAR-Ktech]

Grendel:
Bed Assembly instructions are free when you order any restoration parts. The rear cross sill (under the tailgate) is only available in electro-galvanized steel. It is $125. You can go to the online catalog at www.mar-k.com/catalog , enter your year, make and model and all the parts for your truck will be available on the left hand frame. If you click on the part, it will open a drop down menu with each option available for each part.
Hope that helps.
