Just did mine. I used the washer precision gave me and then one of the 14 ga ones (the thicker 2mm).

I have full clearance now. Good luck.

 

Can someone tell me part number of this this mounting insert, or perhaps someone has two of these for sale!???

Thanks.

 

Mish Mish, good luck on getting the OE part unless you find a totaled vehicle with the wing somewhere.
There's a whole thread in the knowledge base sub-section on this. You seem to be a handy guy, maybe you can make the modify another bolt for this.

The hex bolt thread is a M22x1.5 with a 14mm allen key head. You need this exact size opening to insert the ram connection in to lock. The picture does not show a small rod recessed inside this bolt which allows the spoiler ram to hook onto and rotate to tighten.
If you need more pictures let me know, I will be taking mine apart pretty soon to work on it.
Heck, we should just swap ; my seal grey for your seal grey

 

Mish, I just sent you a PM. I want to remove a set. Any tricks to removing? Heat? Standard threads - meaning counter clockwise to loosen? I put some torque on one and it didnt budge.
Thanks for any advice.

 

More torque! I broke mine free by hand, but it took some effort.
