Trans flush

[buellxb]

Hi,
I went to do my trans service and I seen that I do not have adapter to hook to my trans flush machine the trans line that goes to the radiator is to big for the adapters I have. I was wondering if anybody has some old trans lines that they can cut the ends off where they go to the radiator. I would buy the ends if someone has them. This is for a 04 LB7 Thanks
