That is an interesting question. Of the 1/2 dozen or so sandcast machines I've owned, not one of them came with the rear turn signal assemblies fitted to the bike. I kid you not, not one had rear turn signals. I've had to buy them all off eBay. In fact I purchased that set of assemblies just auctioned by our good friend markivmotors to go on a bike I've just purchased without these items fitted. Would you also believe the mounting bolts supplied with these parts were from something other than a Honda.
Yep that's a good question. Does anyone know if the #8 bolt continued to be used throughout production and if so did a change occur from the large 8 to the small 8
