They can be a pain if you don't do them on a regular basis. It helps to pull them apart Slightly and use a 90 degree pick. The best way I can say to install them is ...just like you coil up a hose or a rope. Start at theend of it and workaround in a circle. If you have a set up that uses 2 spiro's per side...do one on each side, before attempting to put in the second ones! The last onewill be a biittcchh! Take your time. Hope this helps.

pull them apart, stretch them then use a pocket screwdriver and fight with them, one coil at a time, make sure they are fully seated

There is no need to stretch the coil out... You should not be deforming the spiral locks in order to install them...

Simply set one end in the groove, only stretching it enough to get the tip of the end seated in the groove. Then, slowly work the the lock down in a circular direction.
Don't force it... if you damage the lock or the piston then you will be dead in the water until you get replacement parts. It shouldn't take much force anyway.

I use my finger to get one end seated in the piston groove, then use a small screwdriver (a pic would work ok, but be sure not to scratch anything. metal from a scratch is bad for a fresh motor), to work the lock down.
Toward the top of the piston is the tricky part so start on the lower edge of the piston.

Gently pulling up with one hand while pushing down with the screw driver can help get through the top section of the piston.

It isn't really all that hard, once you get one or 2 of them done.

Consider it a form of initiation...
