I have not tried this on a 240z but the arm rest in the BMW Z3's is atrocious! I took the metal bit out of the arm rest and welded a piece of bolt or screw to it. then I drilled a corresponding  hole down the arm rest into the foam. I filled it with epoxy and pushed the screw down into the epoxy to harden. Keep in mind that Z3 armrest are about $200 each not $35

You could try something similar if you could get some wire wrapped around the metal plate or drill some small holes in it. Then epoxy the wires into the foam. I work with spray foam alot at work and I don't think you will have success going that route

Just put your car info in your Sig, and it'll always be there.

I've spent about 10 minutes looking for where I can update my sig, but no luck. Can you tell me where to make the update? 

Thanks.
