WTF with the 5 x 4 BC and getting axles?

Very good question. Now I guess that would make a difference if you went to a bigger drum set with the 4.5 BC. There would have to be a small gap around the drum pilot. Could spell bad news at high speed. Solution could be a bushing around the pilot to match the larger drum? :shaking2:

I was going to stick with the stock original 10" x 1 3/4". I figure since I will have discs up front the braking percentage gained by getting bigger rear drums will not be that significant. Maybe 5%.

I am sending all my measurements to Dutchman and will bring up the 4.5" larger drum pilot hole. :scratch:
