I did not react on your post but I want to thank you, and I will try to make this because the photo's are a great help
No problem Jan.
I am going to try it too. I will be using the torque tube tail drive, which means I will need to somehow secure the crown gear to the tail output shaft (which is made from the 450 main shaft). The stock tail output shafts come with a pulley or crown gear already secured to the shaft, depending on whether you have a belt driven or torque tube driven tail. Any ideas?
