What rear brake with the 450R swinger swap?

[Derrick Adams]

Can I use the stock 300EX Brake Stay and caliper, or do I need the replacement 450R pieces?

Nobody knows if I can use the 300EX components? Guess i'll figure it out on my own.

I have a 400ex swingarm on my 300 and I used the stock 300ex brake setup. The braket that holds the caliper on will need flattened out a little to fit on the 400ex swinger. Dont forget about the bushing on the side of the swingarm or you caliper will rock back an forth.
