lol.. your struggling...
.
create 2 very small blocks. rotate it at the same angle as your shocks.. line it up wherever you wanted it to attach.. rotate it 360.. attach shocks.. attach the remaining block then rotate it 360..
.
edit: I have tried this before and it seems that this setup is prone to making the shocks too stiff.. probably due to the angle where the force of a bump is recieved or probably due to a bug.. I recommend doing some drop tests after you completed your setup.

@BoxGlow Thanks! I've always attached things and then rotated and nudged them to the right place

@Baldovino rotate it 360 degrees, mirror or right-click copy so that its attachment points could reset

After mod rotation it does not attach @Skua @TheLatentImage

I can't recommend the mod that Latent posted enough. I did xml-edit rotations all the time, but even then the mod still made it a lot quicker and easier.

You should try out the rotation and position tool that @HellFireKoder made. You'll be able to easily rotate any piece. It is here.
