Thank you for checking up on this - what am I willing to pay, that is the question of the day, ins't it?! Well, only you and your Dad really know how much extra work is involved in doing this - I am totally willing to buy the Alpine knob from you if you want to sell it once you've got the template made - who knows, maybe you can offer the two parallel models for those that want it? I wanted to buy two faces, the brush and the black - the brush for sure to work with Alpine knob.. Let me know what you think...
