Having trouble getting rubber boot and spring back on

Hi, I'm trying to replace the plugs on a coil on plug northstar and am having trouble getting the rubber boot and spring to slip over both the plug and the coil...Is there a trick to this??  Thankyou for any advise on this

As long a spring is somewhat centered in boot it should be ok. You should not have try attach spring to plug or coil.When coil assembly is mounted, spring should contact both coil and plug.

Ok, thankyou again slowroll.
