I don't even have to look at it to give you an idea.
Handling wise....
If it's been spring lifted, or especially shackle lifted, see if there are shims under the axle perches. If not, you'll need some. It's a good maintenance practice on all cruisers to adjust and lube the center pivot arm. It's had play on every one I have ever owned. Also check the ball and socket joint on the drag link right where it meets up to the steering box. If there is any play here, it can be adjusted out with the giant screw on the butt end. If no adjustment is left, look up the 2 penny fix. And lastly, if you have never replaced the tie rod ends, just go ahead and do it. They aren't that expensive and they make a huge difference on most any cruiser.
Now on to the ride....
Look and see if the springs are stock or aftermarket. If it's stock, check the bushings at each pivot and see if they are worn out. Also, check to see how much travel the axle has before hitting the bumpstops on the front axle. If it's an inch or less, your stock springs are toast. Now, if the springs have been replaced or the truck lifted, count the spring leaves. The more the merrier. If any of the leaves are much thicker than the rest or you only have three or four leaves, there's your problem. Good leaf springs have lots of thin leaves.
