I see no point in chasing numbers with your proposed set up as the differences will be minimum and I doubt if you will notice any difference when on the bum dyno.
Go for what is VOSA friendly and what sounds best.
I can't help you with a recommended repairer, however I am dismantling a 07 313HR at the moment, so I can supply a fully working CD drive/unit.
Just drop me a PM if I can help further.
Alex.
PM received and replied to:
I have at the moment:
Wing
Mirror
Air bag
SRS ECU
Wheel
A pillar trim
Door glass
New would be circa £2750.00
Genuine pre owned would be £1250.00
Regards,
Alex.
OP: I have provided the part number twice already, perhaps 3rd time lucky:
The part number is 96022-CDE000
Best with brand new, direct from your local Nissan dealership as used are always rusty.
Okay, what do you mean by front lip ?
If it is the front air spoiler that you are referring to (OEM) then the clips are metal and you will require 7 of them and the part number is 96022-CDE000
I have a pair of replicas which are about to come off a car and they are a perfect fit.
Drop me a PM if I can help and I will ping over some images.
Alex.
