I'm switching out my ATE brakes to the Bosch brakes on my '79 RT and I don't really know the year of the newer lowers but they are different than the ATE lowers. I don't know the year on the Bosch lowers, but would like to know what fork brace might fit. Is there a generic size brace for the lowers? I figure it has to be an early 80's set of lowers, but can't be sure. Appreciate any recommendations.
