Sorry my 2007 build has captive nuts so access was from the outside. ISTR others have had the same problem.
Re RIF's fog and reversing light blocks. I was under the impression from 666 that they were using RIF's molds for these? I was also told they were V tight but did fit. This wasn't a problem either? Nice snug fit but not really a problem.
Once the rear light blocks are sorted I have the indicator pods to do. Haven't looked into how easy this is I'm hoping its an unscrew, unclip the connectors, unbolt the old pod, feed loom back through and refit headlight.
If I have to get involved with realigning the headlamps I suspect it will be a pain.
