97 F-150 5.4 Triton changing plug probs

Well 7 are done ... but the 3rd one back on the drivers is impossible to get to. Do I have to take the fuel rail loose? Any complications from removing the bolts on the rail? Will this even give me enough room? Any suggestions from anyone would be helpful.

Thanks

Removing the bolts on the rail is not a problem. just remember to press the rail down on the injectors after your plug work is completed.
