I did pull out the seat yesterday and found the source of the odor! Bones (yes, bones) fell out as I pulled the bottom bench seat from the cab. Good thing my brother brought his hazmat suit from the firehouse!

But now that the bench seat is out, there is a considerable amount of extra space to move around in the cab. I'll get to those dash items today. I'm hoping to take them home with me and work on them throughout the week, as it's not always easy for me to spend time in the garage during the work week.

Thanks again!
