OK before this goes crazy, let's clear a few things up here.
Many of you will disagree but I don't care cos I know I am right init?
The product is called a bush, bushing is what you do with it.
Unless your American in which case a tyre is a tire, burr is burl, grey is gray, and your brother is your lover, you need to be forgiven for not speaking English.
Bush's grow in the ground, bushes are machine parts, spacers / packers / shims for rotating or moving parts.
45° angle on bush is not gonna mate very well with a 60° centre, probably worse than having a hole in the end which should also be tapered to suit the mating parts.
I close with saying why should I pay extra or have especially made precision bushes? They should all be precision made from the word go, if they aren't, complain, smarten your act up and get them right to start with.
