changing glow plugs

[07 grizzly700 BE]

So yesterday i had some time and started replacing de glowplugs with Delco's. I started with the 4 front cylinders , wich went pretty smooth. But then i started trying to remove the other ones, and it seems i can't get to fit my wrench good enough to remove them. Did any of you guys have to remove some parts from the engine bay to get to the plugs ? Because some are in a really tight space, where it looks impossible to remove them. Or do you you have to remove some from underneath the car ? Any advice would be appreciated!
Thanks in advance
Matt

Are we talking 6.2 or duramax?
On the 6.2 the rear ones are easier to acces from the wheel well side.
I did remove the inner fender once to have better access but I also have a turbo that makes things even tighter.
