Question about boxster struts
 

Im working on a 1974 vw 412 and I think I want to use 96-04 boxster parts for the front suspension. So i have a question.

What is the distance between the lower spring seat and the spring hat when the strut is loaded, or in the car wheels on the ground.

What is the distance between these two points unloaded.

What is the corner weight for the boxster in the front? And if this is known then what is the rear corner weight?

I did a search and found the corner weight for an 02. Now just need the compressed and uncompressed distances.
