Well obviously you don't, you obviously got scammed you idiot. The Funday has an Odyssey Director fork, which doesn't have brake posts or a typical bmx dropout. Also, I HIGHLY doubt the downtube on the frame has the wave pattern that is on all Sundays frames to keep the downtube from denting. One more thing, that is NOT a Sunday orange paint. This one is darker than the typical Funday paintjob.
funny how it look exactly like the other bmx in your for sale folder try looking at a sunday funday frame and you can clearly see the rear triangle is totally different to a sunday funday the chain stays go up at a slight angle yours dont its not a sunday dude except it
