Speaking of fun with center rear lines, I finally replaced mine. I’d ordered stop tech SS lines before I’d heard of he goodridge line fix. Didn’t put them on the same time as my fronts because the bleeders on the rear calipers snapped off, so I got new calipers all the way around now too. On the center rear lines I figured I’d just put on new ac delco lines. Rock auto only lists one line from ac delco, for active brake control / stabilitrac. Most other brands also only list one line, so I ordered 2 ac delco 18J4222 lines
Here’s the mounting brackets…

…so the locating slots are different for the center right vs center left. The 18J4222 is a center left, and rockauto doesn’t list a ac delco center right, and I don’t know if they even make one. It looks like centric is the only manufacturer of rubber lines rock auto lists with 2 different part numbers, calling it 15” and 15 1/2”, looks like 15066404 is their center left, and 15066358 is their center right. The stop tech lines I installed at the 4 corners don’t use the locating slots, and I’m guessing other SS lines might avoid this issue at the center lines as well.
So I went to orilleys, figured I could get the right line for $10-15 there…. They had a similar listing as well, only one center line for stabilitrac. They also listed a gm 2 line assembly with brackets for $154 plus shipping plus tax, and in 2 days they could hear back how long it would take to get…
So I went back home and started grinding…

that’s all it takes to use 2 center left lines. I guess gm didn’t want anyone to accidentally cross the lines. If you do end up grinding yours, be mindful of the orientation so that the line isn’t twisted, the lower end I thought was just a hex at first glance, but it’s not.
anyway… finally driving on SS lines at all 4 corners, and new rubber center lines. The brake pedal is now almost weirdly high and firm, but I figure that’s a good thing.
