Alright folks, many of you know of me and my truck. At least I hope you do...

It was keyed, and is currently being repainted. I want to put the QX56 wiper cowl on it colormatched. There are some issues, apparently
The body shop has both the Titan and the Infiniti wiper cowls, which they told me was received through a dealer who cross-referenced the part numbers. Upon rough fitting the QX cowl pieces, it appears there is too large a gap on one edge and where the hood meets the cowl when it's closed, the cowl interferes with the hood closing properly.
I am going to the shop first thing Tuesday morning to see the issues and make a decision how to proceed, so time is short. Any one who has done this swap, if you can chime in with information, I'd appreciate it. Any information regarding fitup or modifications would be helpful. Also, if anyone can provide me with specifics such as the EXACT part number and if it worked exactly, would be great.
My truck is a 2006, not that it matters and I know the later models, 08 for instance, aren't interchangable, but I always thought the 2005-2006 were.
Another thing that would be helpful, if anyone has colormatched the Titan cowl, did you sand it all smooth? The pebble finish is in all the grates and fins and would take forever to sand smooth. How did you handle this? And any closeup pics would be highly beneficial if possible.
I appreciate all your help on this one. Although it's not an earthshattering decision, I'd like to get the QX cowl to work if I can. THANK YOU!
