Identifying a Dana 70 rear

I think I may have found the Dana 70 that I need to convert my '83 K20 to a dually. The rear is laying on the ground though. How can I tell the difference between a dually 14 bolt and the Dana 70? I'm keeping my bed so I need to make sure it's a 70. Also I've done tons of searching and I THINK all I have to do is move the spring perches and shock mounts on the 70, right? For some reason I'm afraid of moving the perches closer to the backing plate and then having the inside tire rubbing the springs... Does anyone have any pictures they could share of the results of doing what I'm planning?

Thanks!

The 14 bolt has a bolt on pinion support and the dana does not.
