Sorry, I will have to disagree here. I'm the first to admit I'm no expert but I do not think the bleeder valve thread size has anything to do with the brake lines and the banjo fittings and bolts themselves (754 - I'm sure he means the banjo fittings when he says hard leads). Banjo bolts on these bikes are pretty much all the same size, when you buy stainless steel brake lines they differ in number of hoses, hose lengths and the angles of the banjo fittings. One thing you can do is send the exact measurements of the lines in your system and the angles of the stock banjo fittings to your Galfer reseller for them to match up against, the cost is not much different to get them made to your exact spec.
I'm not sure about Galfer, but a couple of these Stainless line resellers actual make the lines themselves, they just get the specs, fittings, hoses and a tool from the manufacturer and make them to order.
I also know that the information Galfer has in their list is not 100% accurate, for example they list a 79-82 GL1100 set. There is a 79 GL1000 and an 80-82 GL1100 but no 79 GL1100. Also the 78 and 79 GL1000 use the same brakes, clearly either the years or models or both are wrong on their list.
Hope that helps, don't stick your banjo fittings in your bleeder valve holes though

Isn't there a 73 500 twin? Maybe that's what the Galfer kit fits?
