Picked these up cheap locally. They have regular spring seats but have some collars to adjust coilovers? Basically what are these, what are the limitations of this type and can I get them to work with my EE?

For those who don't know Wagovans use different suspension...im not sure if they are longer but I think perches are different heights.

 

all the 89-91 civic suspension fits. obviously the 88 rear LCA’s are different.
