Interestingly, the spec never change but many do report being able to get more caster on the later models. Spec was 3 degrees static in 73, backed off to 2 degrees static for the rest of the production. Likely they found the 3 degrees put too much stress on the steering components. Remember, these coaches were designed for bias ply tires which behave much differently at speed than the radial tires most use today so you need up to 4 degrees static with radials to accomplish the same caster at speed as 2 degrees static with bias ply tires.

No offset bushings. It is a 77 so did later builds have more?
