Measure the distance between the holes. International standard is 51mm and prior to that it was for the formula pattern of 47mm (might be 48mm
Problem is if its the latter is finding an adaptor to er... adapt it to fit a no5 caliper with IS pattern.
This place really surprises me at times
People here have cnc parts made and some can even do it themselves with their own machines. Yet to see any mass production of them even though the problem exists.
That said there was a guy on ebay selling some from the ones he made but he was exploiting it somewhat and asking a totally ridiculous price
$75 or something like that.
I have an amp fork which has a mount that is near useless for anything other than amp brake calipers., however there is an adaptor for it and im lucky enough to own it. Im intending to reproduce as many as i can as cheaply as multiple copies will allow.
Then offer them here for the percentage of the total + Postage.
Just getting confirmation on the alloy to be used, likely though anything modern will be a vast improvement on the original .
