As the cost of shipping for small parts add up, I finally broke down and bought one of these....
Alpha + Spare Parts Kit
This kit includes the following parts for the Alpha+: 2 molded nose pieces, 2 30 cm long pieces of black line, 2 leading edge connectors, 1 upper-side bridle line, 4 6mm nocks, 15 7mm soft end caps, 2 6mm spar-side stand-off connectors, 8 2.5mm sail-side stand-off connectors, 1 6.1mm aluminum ferrule, 1 O-ring for upper spreader, 8 6mm stoppers, 4 3.5mm end plugs.
Don't believe the LE connectors on the Alpha+ are APA.
The sizing for APA equivalents are here (pretty sure it would be an APA "B" connector)http://www.aviasport.net/catalog/accesories/parts3.htm
I think the angle might be a tad different, so you might want to do both sides if you are switching to APA.
