I just finished making a mirror mount for my 8500 x50 and i am looking to see if anyone is interested in one.
They will allow you to mount your 8500 or any escort radar detector to your mirror.
I would imagine they would end up costing about $35 if i can do about 25 of them.
They are made out of aluminum and will have a 1 1/8" hole in the clamp to mount to your mirror. Ill post pictures after i get it installed tonight.
