Update

Finally got round to fitting the bush today.
Basically I just drilled the heads off the rivets and used a punch and hammer to knock them through seems a waste to throw all the joints away but there is no way any of it will fit so in the bin it goes, lol.

The holes on the bush do not line up 100% but I put the bush in the vise and squashed it only a small amount and then the holes lined up so nut and bolted it and then turned 90 degrees and squashed again to do the other piece.

The finished piece...





Good as new and feels very tight
