GM factory front spring #400882 - looking for the Free height of the spring - Spring was used in 70 for C/S with HT SB with A/C.

.thanks

 

According to the catalog free height should be 17.170, load height should be 11.000, Wire diameter is 0.640

 

That appears to be moog data. thanks. Maybe a new spring #5374 is the same as original...., but finding out the free height of the original GM spring is what I am after. thanks

 

It is from an old Moog Catalog from 1991 which at the back had a section called NUMERICAL INTERCHANGE LISTING with the Factory Part Number to enable you to research the stock springs. It even includes the Separate part numbers for the left and right springs.
