Hi Paul
I thought that you would respond
I am only looking for a close approximation. I am trying to work out how much I can reduce the weight of my prioject car. I am now using a BG T5 in place of the original 4 speed 2000E type box. I need to know the weight in order to work out how much extra the T5 weighs. I believe it was 23 spline. I sold my box some time ago before I became obsessed with weight reduction
