I know this is an older thread, I just wanted to add another thought.

These trucks are old, and with time, use on the farms and stuff the springs will loose their rigidity over the years. For example a 68 model truck, new would sit quite a bit differently than it would 54 years later.

Just keep in mind if you buy new drop springs, that measurement is taken in comparison to a new spring. Stock vs the drop spring, it will sit 2" lower yes. But it is not measured against a 54 yr old sagging spring. It may sit 3/4-1" lower. It's a lot of work to lower one regardless but just know that 2" drop may not give you a true 2" net drop.

As others have said, using a drop spindle it's going to be a true net drop. 2" spindles will give you 2" drop. Be careful with 15" wheels, especially 8" rallies if you go with drop spindles. This is why a majority of the trucks you see have larger diameter wheels.

4.5" / 6" drop looks really good on these trucks. Just my opinion.
