In what year did GM change the rear brake lines to metric sizes with a reverse flare? I just installed a rear end today and had to change over all the brake lines to work with my '82 Camaro. I don't know what year car the rear came out of but it has 3.42 gears. Thanks for any help.

I think it was '84.
