Hi Bruce,
You've seen the photos of my bar in the other thread. Any particular questions I can help with?
I fitted it myself - photos of the process (which I don't think I linked to in the other thread) are here:
http://www.pcoa.org.au/forum/viewtopic.php?f=19&t=4203&start=30#p37775 . It's really not as hard as you think - if a numpty like me can do it, anyone can. You just take your time, and everything works well. I think mine took me about 3 or 4 weekends to prep, paint, install and wire up. But there's really nothing difficult about it, just time consuming.
Ours was pretty easy in that no trimming of the front bar was needed, one of the benefits of an older car I guess. The only real issue was that a couple of the holes on the bracket weren't in the right place, and I needed to elongate them with a $20 die grinder. Initially I thought our car might just have had a nudge in the front previously, but other Pathfinder owners have since confirmed that their cars are the same, so just a slight problem with the jig at the factory.
Going to order a polished alloy bar from MCC for the father-in-law's Courier shortly. They're one of the only people who do a bar for that model, and they're priced well. We'll be fitting it ourselves too.
Good luck!
Matto
