So, I wrote that guide as I work almost exclusively in puchs and the main takeaway I was trying to convey was the relation to which forks go with what fenders.
Free spirits have two different forks and only the regular free spirt uses the combos it does.
Free spirit deluxe uses the exact same fender and forks as a magnum 2
Regular free spirit has a lower fender brace that is exactly like a maxi lower brace except its much shorter and it mounts to small tabs on the back of the forks instead of he axle.
As far as the deluxe/magnum 2 fender is concerned, those rivets always get loose and rattle like hell. Drill em out and replace them with hardware.
Either way, there is no direct aftermarket magnum 2/freespirit deluxe option, but those do allow the resuse of your old fender due to thier rear tabs.
If your regular freespirit forks get replaced with ebrs, they will need lower braces from a maxi, freespirit deluxe need those tabs to work
