Does the moulding of the poptop roof sit in the guttering? from looking at pictures I suspect that it does! without the 2-3cm gutter width there isn't anything for the Fiamma bracket to sit in.
As for the 2.6 versa's 3.0 metre debate, I'm going to hang myself here, as for a long time I always recommended the shorter 2.6 metre size for its better looks when fitted. I actually owned a Polar White F45Ti in the 2.6 metre size for several years that I purchased new. However, I have recently (about 5 weeks ago) sold the 2.6 and brought a brand new 3.0 metre F45S in Black. So you see I am uniquely qualified to comment.
The only issue...and it turns out to be quite a biggy, with the 2.6 version, is that it will leave the sliding door exposed to rain, as when fitted (as far forwards as it can be) the canopy only overhangs by a matter of 15cm or so, not quite level with the door. When it rains (anything more than a drizzle) rain comes in through the sliding door.
The 3.0m F45S extra 40cm takes the canopy almost half way across/above the front door, offering vastly better sliding door protection....just a fact.
Oh and I just remembered...the 3.0m extends 2.5 metres outwards (the 2.6 only 2.0 metres) making the overall canvas 45% bigger (4.9 m2 compared to 7.3 m2)
Hope this helps.
First pic shows my F45Ti ...you can see how the canopy section just goes a little over level with the door.
NOT SO CLEAR! but you can just about see (behind my Hope Burner) how my new F45S 3.0m extends well over the door...past half way!
