What I will have is a blanking panel which covers the 3 x switch apertures so if my memory serves me well the switches have to be removed so that the blanking panel is a good fit.
Library pictures from a DE below to give you an idea.
I have the blanking panels that cover the 3 switch apertures in the centre console it that is what you are referring to.
Might be a plan to post up a picture so that we are on the same page.
The quality is better than OEM and in particular the seals are manufactured with neoprene and will not leak, which is a flaw with the OEM covers.
I have been selling and fitting these for over 10 years and I have not had one failure or complaint.
The rear toe adjustment is made by adjusting the rear mid link by the bolt in the subframe.
If the edges are off the subframe flats then you have the options as listed above.
Some prices for you:
1 x good preowned rear subframe: £75.00
1 x new tow bolt kit (for both sides) £32.00
1 x new lock out bolt kit. £65.00
2 x rear adjustable rear mid links (for toe adjustment) retaining the OEM spring position. £760.00
The replacement subframe and the new toe bolt kit is the way to go.
All the above parts are in stock so just drop me a PM if you wish to proceed.
That is an image of an OEM genuine Nissan arm with the correct recess.
You will probably find that the eBay arm that you fitted will have a deeper recess which will be obvious.
You will have the same fitment issues on both sides.
There are 2 x types of transverse arms and you will probably find that you have fitted the wrong one.
The difference being is that the recess for the ball joint nut has more of a recess and you require a different seating cone.
Usually the eBay transverse arms are not compatible with the OEM seating cones.
Wrong size of seating cone fitted to new lateral arm.
Or suspension upright lower ball joint failure, however I would be firstly looking at the seating cone.
Your mechanic may be referring to the flats on the subframe which the adjusting washer pushes against to make the adjustments.
The subframe is aluminium and so are the flats and I think that he is saying that the flats have lost there edge so the adjusting snail cam washer is not making good contact when the bolt is turned.
Welding can be done to reinstate the edge but it is a specialist repair.
The other options are to just fit a good preowned subframe which I have in stock.
Or you could replace the adjusting bolts and washers with lock out bolts and washers and then fit adjustable arms which I also have in stock.
If you require more clarification on this just drop me a PM.
All parts are in stock and good to go same/next day.
These are aftermarket lights and therefore I can not offer any informed information on them I am afraid.
My comments above were based on them being 350Z OEM 2006 up, Bi Xenons.
