Finally - new crancked trailing arms

I was studying all types of trailing arms those are on market (and few custom) whole week and I decided that I will try to make my own arms. Ive bought tube on friday and got spare ones for mesurement. I used original ends from them. ive welded them on 42mm tubes those are curved and strengthened (as you can see below). They are working as Ive expected and will see how long will they last… just hope I wouldnt lose my rear axle :D
