[Closed] tweaking a Trek Top Fuel

Been making a few minor tweaks to the setup of my Top Fuel.

first the triple is now a double, still the same XT cranks, 40/26 and the 11-32 cassette has now grown to a 11-34. So that should be fine, noticed that the 40 is getting quite close to the limit on what the chainstays will allow. Does anyone know what the max chainring the frame will take?

I have also reduced the forks from 100mm to 80mm, the cotswolds are smooth-ish.

Few things, is it worth me dropping the front mech, just i need a new gear cable to do this so whether i need to go into town to get one. And does anyone sell just half a chainring bolt pair? i have 4 short outside bolts but i don't have the short inside female part, well i have two but need four.
