I dont think the problem is with the lines themselves, I am looking through different pictures right now and it looks like the tee valve is positioned in a few different spots on these housings. I know I have the right length housing, so that isnt the problem. Look at the next two pictures I post, both of these are 1969 B body 8 3/4 axles with untouched tee valve locations.
