I have done the searches........
Thinking of lowering my classic wagon, found reasonably priced eibach and tein kits, but i need to know either briefly how much work it is or a step by step guide would be great thanks

 

Pretty simple really. 3 bolts up top and two at the bottom to remove the strut. If you're just changing springs and not the struts (maybe for coilovers) then you'll need spring compressors for removal and refitting the springs. The geometry will need fully redoing afterwards.

 

Easy job, mine took me two attempts, but that was because i tried to put the rears on the front

hardest part is undoing the bottom bolts on the strut IMO
