Hey James,
Your right, it's not to hard. I just posted aking this a few days ago or so. Putting the new one in is tricky. I had no instructions. I ordered the line from Jim carter. Chevy of 40s has one part in the kit back ordered.
I am going to post pics tommorrow night as I photo documented mine step by step. Take your time! Remember, you get one shot, or you have to order a second line kit. Good luck and keep us posted...
