bucket seats in GMC 6000

[Mr Diesel]

I was strolling through a local scrap yard and saw an 80s model GMC 6000. It had bucket seats inside. Are the cab floors the same as the C/K series? The doors, dash, and instrument panels look perfectly interchangeable with the C/K series, so I'm wondering if the bucket seats are a direct swap too. I don't need another set, but might be able to pull them for someone else.

Cab floors are flat, our trucks have a hump for the fuel tanks.

Thanks! I thought they did look a little flatter...
