He has told me that he can no longer use his company's machining equipment when off duty. He is an excellent 20 year machinist but he no longer has the tools.
He has the plans though and advised he has a friend who can make them but would probably need to make a few sets to be econonical. With the other guy making them it's no longer a car guy making them for his brother and his brothers friends.
I suggest you just contact him directly...he'll do all he can.
