You've got plenty of time yet. You just want to have it drilled preferably prior to painting the interior, which given that you are building a slider, should be about the last thing you do before you rivet on the F-7106 forward top skin (for access reasons). Before you get to this point make sure you have pre fitted your fuel lines, rudder bar (then removed it because you will need to get in there to buck rivets), drilled all the required holes in your firewall and mounted any doublers, put the belly insulation on (if you are doing it) and prepped the materials for the firewall insulation (but not yet installed). The arm rest should Not be riveted on until you have installed the canopy roll bar, as there is a nut holding the roll bar down on both sides that you will need to access. Once the F-704k is riveted on, you will lose access to this nut. Basically, prep/paint your arm rests and F-704K, but don't rivet them on until right at the end.
As our American cousins like to say, your mileage may vary (the metric version of that saying just doesn't seem to work).
