Well im just gonna pull the bed all the way off and make this easier to swap the bed wood, tank, sender etc....grabbed a come-a-long and lifted it up in the garage and roller her out into the sun again.

I definately can tell someone has swapped frames now and built all different mounts...and its been shortened right behind the cab. Hmmmm turns out to be a 78 K20 chassis
