Price Pfister Pull-Out Faucet Spray Head Replacement

I bought a brand new "generic" replacement pull out faucet spray head to replace my Price Pfister that is yellowed. The PF has a straightforward male/female connection joint to the spray handle. Based on the enclosed picture, how am I going to get the male end into the new white generic spray handle? Is there any part that I need to remove on the new handle? If not, is there an ingenious way to use this spray head for another purpose?

Call up Price Pfister for the right spray head replacement.

You cannot. Call 1-800-PFAUCET and Pfister will send you a new head.

Thanks guys. I called PF and a new replacement head is on the way.
