escort van 55 or 75? difference?

[ColJack]

what is the differnce between an escort 55 van and an escort 75 van?
is it just the load capacity?

this would just be the springs right? or is there more to it?

It does refer to the load capacity - and the spring ratings are different.
Early Escort vans had different rear brakes and compensator, but I can't comment on later models.
