piranha hull pump shoe issue

Trying to fit a pump shoe in a piranha hull. Pictured is a 155/160 rrp shoe sitting in pump cavity. No wjere close to fitting. Does anyone know what they are running for shoes or how to get ahold of the dude?

@gsxral1000 might know?

Get it set exactly where you want it and then pour Epoxy Resin in to fill the voids!!!!!!! then sand smooth...................

What the hell was in there before?
