Good day sir, Took quite awhile to get those bolts done and am happy to say they turned out perfect. Unfortunately I probably won't be getting any more done due to numerous reasons but main reason being the time it took him to get them done for me. Machinist is a good friend but he lives 1.5 hours round trip from me and chasing him down to get more made up is not in anyones best interest ,especially mine when it came to the time to manufacture. I think you will find very high quotes to do them but not because of the difficulty but rather large machine shops just can't be bothered, not enough money, simple as that. If anyone is interested when he finally got around to doing them he used oversized grade 8 bolts to duplicate the originals(only way to maintain oversized shoulder with 7/16" fine thread), took him a little over an hour to do four and charged me $60. I'm telling you this to give you an idea of what is involved if you need to get a set made up for yourself. Hope this helps, sorry I couldn't help more. Kevin
