Richard gives some good advice. I have found that the 8" brakes are, in general, really well made. I had the left side brake arm gall in the boss. It is best to check everything for fit and lubrication. I also had to remove the external springs to get correct braking, however I know others who kept them and were able to set them up properly.
The brake cam is an original component, but has a slightly more square profile on the cams. The outer cam bush is stock but the inner cam bush is special. It has an 1/8" lip on it that sits inside the plate when installed. This lip places the shoes at the correct height in the drum. You can use a stock bush, but you should put in a 1/8" spacer to keep the shoe in the correct spot.
The scoops and the retaining screws are non-stock, but can be interchanged with the correct screw threads used. The 8" scoops have a curved edge and the stock have a straight edge, but are otherwise the same size.
The above brake plate is different than the one supplied for stock bikes. It does not have the water excluder machined in it. I don't know if they are available through the club, but it is worth asking if you think it will better suit your needs. Available in polished also.
