Emergency Brake for Lifted Blazer???

[Critter]

Ok, I need help. I have searched the forum and vendors and can’t get a straight answer. I have a six-inch lift on my K5. I need longer emergency brake cables as the original ones are stretched to their max. I don’t have a truck around to compare to but my understanding is that the rear of a truck, swb or lwb, are both longer than that of a Blazer. My question is how much longer are these, if any? Then, where do I get a new set? I have looked through a couple of catalogues and a lot of the site venders, but I haven’t seen anything that with a description that I am comfortable purchasing (not sure if I would be getting the right part). I’m sure someone else has gone through this before.
