Kelsey Hayes caliper bolts

8.50 is a great price, I would be more than willing to buy them when I need them. Question..could you not just turn down and tap a std grade 8 shank bolt (or even sleeve a 7/16)? Rolled threads would be stronger than cut threads but seems the shank is either a strength or a positioning aid. Either can be overcome with a stronger bolt ($$ in Mopars eyes) or maybe a positioning dowl (like a head). Im not an engineer (only a manufacturing process student) but just looking at the bolt...?
