Passenger side, two piece floor pan tie in

[Jeep Slayer]

Pretty much have my floor pans, ready to drop in to my 67. My question is on the passenger side the front floor pan does not overlap the under seat, floor pan. the support only supports the under seat pan, but not the front and it does not overlap the under seat pan. Seems to me that there’s no support for the back edge of the front pan. Any ideas?
Thanks
