stolen 8 3/4 third member

someone in the ups store number 5252 in st louis MO STOLE my 8 3/4 third member with eaton/ detroit posi and 3.90 gears now I have to go through the drudgery of UPS claims .So anyone in MO please keep an eye out for someone trying to sell it.
keep an eye on 'offer up' and facebook marketplace. Also, make sure to peruse other posi, tru track, .....basically ALL chunk ads as they may not know what they have. AND I would keep checking for awhile as many theives will post ad after they think its 'cooled down'.

Any identifying markers?
