Where did you order the lines? I was looking for new pre-made lines when I was adding mine and the price of the line wasn’t bad but I remember the shipping was more than the part and drove the cost higher up than I was willing to pay. I ended up going to twilight zone and buying two straight pieces of steel line and bending my own. There is a junction where they meet that I was a little worried about but it’s never so much as had a drip. I would liked to have had some of that spring protector on it for the exposed areas but I think I used something else(can’t remember now). Came out perfect if I do say so and only cost me about $16 IIRC.
I have to install a return on the 67 because it was a 326 car and never had one but it’s got the 400 now and will need one now. I’ll probably do the same thing again unless I can find a screaming deal on pre-bent cheap enough.
