Front coil springs

[leddzepp]

I purchased a set of 1" drop coils on the board recently, and believe they are actually 2" drop. Reason being I swapped them in place of my current drop springs (which I am pretty sure are 2" drop) and the height stayed exactly the same. These springs measure 12 3/4" in length. Anyone have a measurement of an OEM length coil, or a "known" drop coil for comparison? There are no markings on these and I'd like to pinpoint what drop they are exactly. In any event, I need to go up an inch in the front and will be listing these on the parts board for trade for what I need...which will be 1" drop coils if these turn out to be 2", or OEM length if these are 1" drop. Here is a pic. Thanks in advance.
