<DIV>This is just from memory. the BN1 plates will have 3/8" diameter holes
where they fixes to the stub/swivel axle. Later ones are 7/16"</DIV>
<DIV> </DIV>
<DIV>BN1 original part numbers are Girling GB40744-5 should you find any
numbers. The last number denotes left or right ; I cannot remember which off
hand.</DIV>
<DIV> </DIV>
<DIV>I was of the opinion that BN2 and BN4/6 wire wheel were the same but I have
checked and they do seem to carry different part numbers.</DIV>
<DIV> </DIV>
<DIV>Only part of what you need in the way of information but this might
help.</DIV>
<DIV> </DIV>
<DIV>Best regards</DIV></DIV>
