Coolant reservoir level? (no cold fill line)

Hi there, So I just picked up an 03 mustang gt 4.6 and did a coolant flush.. I am looking a this coolant reservoir and not seeing a lower cold level. Just an upper line with an "add coolant" about a quarter inch from the top. The manual even says ad to the lower cold level... Maybe someone put an after market reservoir in this thing?
Where should I top this thing off to. Thanks in advance..

The "Add Coolant" line on my 2K is 3/4" below the black top. Cold my coolant is at the "Add Coolant" line. Been that way since I last messed with it 2-3 years ago.
