Try Longbox55 way first.....
I have a fellow bolter nearby. A young man who doesn't post much but he just finished having his 68 axles drilled out to five lugs. He has a friend who works at a machine shop and did them for him. They look excellent but the proof will be when he gets it on the road which may be a while yet.
Maybe not a LOT of folks do it but it is being done.
