New Brake Drum

I expected putting the new brake drum on to be a 5 minute job but as always not everything went to plan. When I went to put the drum on the first time the studs didn't line up. I thought that as the wheel had been on without the drum the studs hadn't bedded in straight, they didn't look like it anyway. I then proceeded to destroy the threads on the studs and nuts trying to pull them back through so I had to get 5 new studs and nuts. These studs seemed much better quality than the ones the replaced but were, again, unbranded. Replacing the studs didn't work. I then drilled out all 5 holes to 19mm to get the drum on but it still took a mallet to get it over the shoes. I think that both the hub and drum were just crap. I know the drum was Britpart but I don't know about the hub. I should have simply found a series 2 hub in the first place rather than substituting a series 3 one. When I rebuild the rear axle I will find a secondhand series 2 hub and brake drum rather than using the ill-fitting series 3 hub/drum. I guess the lesson learnt is to get the right part and try to go with good quality parts rather than the cheapo Britpart stuff.
