Could it be that the older 28.5mm ones were actually imperial 1-1/8" i.e 1.125" ie 28.57mm.
Mike, were your bolts metric or imperial?
You might find that the older bolts were imperial.
Does anyone know if it was the older bushes that were 28.5 mm or the newer variants.
Just had a look at my bolts which are metric and I'm going to guess that my O/D would therefore be 27mm. (How's that for backing ones own hypothesis based on nothing more than guesswork)
Pure speculation but I wonder when MMC changed over to metric on these bolts.
