lower the box
NO need..
am I just talking bollocks again?
Probably not. it does make it easier to get to em. But I find a couple of 8" bars on a ratchet makes it simple enough to do without having to drop the box down.
have done it this way myself, just find it easier to lower the box
If yu take the bottom three bolts out and replace em with x 6" lengths of threaded bar. It makes it a lot easier to remove, and to replace the box later. as everything lines up .
