So, it seems the rear shocks that were on there were too short.

60-62 GMC and Chevrolet's don't usually have rear shocks listed at all the usual places.

I found one posting that pointed towards some Race Car Dynamics Bilstein shocks that fit (Part 55-R148) .

The before and after is quite noticeable.

Thanks all for the responses and suggestions!
