Each of the five frames has a slot in the bottom with studs
that can be inserted in hole and the slide along in the slot....My side frames each had four studs. The most forward one came through into the cabin. The other three were accessible under the gunnel. They just had lock washers and nuts on them. The front frames in front of the helm and passenger seats have what looks almost like a pipe that slides up into a bigger pipe on the side frame. It's a pretty snug fit....but if you took the 4 nuts off the side frame would slide up and back and would slide off the front frame. I'll post some better pics if you want....
