I'm doing a slider on my QB fuselage, and the forward skin came with my fuselage kit. I think for the F-705, the QB should be without rivets in the locations that would be used to attach the roll bar part that makes up the back portion of the canopy. On my plans I just fill those holes in with more rivets since I don't use them.
I also remember there is some detail on two small plates (

The last detail is probably in the first top skin behind the cockpit. In order to do the slider there is a doubler plate that supports the slider guide. I haven't gotten there yet, so I don't know exactly what needs to be done. Tonight when I get home I'll look at the packing sheets and see if there is anything else that jumps out at me. My plans came with both sets and a bunch of notes to do X if you have slider and Y if tip-up.
