Aaron,I believe they are gold plated and jewel encrusted which is awesome for bling value but my engine bay is quite ordinary so second hand at $30 each is me!
Seriously,I will keep making enquiries until I find a suitable local affordable mount which will do the job and make them or their source available to this forum.Unless one of our more knowledgable members can save me the work??????
Cheers.Pete $250 is tooooo much!
