If those were advertised by Allport then i think we all need to think carefully before buying anything that he/she sells in the future, even if that have been advertised for a mate.
And to his mate who sold them on, YOU ARE A FOOKING TOOL.
Selling something in that state is unsafe and unfair, if you **** up a piece of kit through your own stupidity then don't try to pass it onto someone else, throw it away and if you can't do something on your bike then get your LBS or mate who can to do it for you you tight git. If you bought them like that then more fool you for not taking it up with the original seller.
To the OP – if the seller you bought off won't refund you a fair price for replacements then for god's sake replace the steerer/uppers before its too late.
