I found this on an eBay seller's page:
My advice is: If the existing standard bracket bolthole pattern does not match your reader, do not suggest/infer/hint the problem is solved with zipties.
One of the risk of buying knockoff replacements is that 'minor' details like thread patterns and hole locations are often slightly 'off'. It is one of those hidden costs that can make a 'great deal' a profit sink on the jobsite.
