Ground clearance questions

[jjstang 55]

Over the years I’ve made changes.  1” lowering coils, Shelby drop and now 17” 234x45. 
I’m hitting the ground occasionally so I am curious of how much it has dropped drop stock.  
I measure 23 1/2 from the fender lip to the ground.  Can someone tell me what the stock measurement is?  TIA

From the Chassis Assembly Manual:

Standard suspension 27.02"

GT & IMP, Handling 36.72" (obviously an error- it's probably 26.72")

Competition 26.62"

all are +1.00, -0.70

Mine is still stock with 14" rims and 27.375".
