inline tube brake lines dont fit!!!

[lost wages]

i bought a set of stainless steel brake lines from inline tube, like every real hotrodder, they set in the box for almost a year before i got around to them. The lines for the rear axle pass each other by about 6 inches, they ore to long, my truck is a 68 with a 71 rear axle, i emailed them and told them my problem, no reply, called them and told them my problem, they asked me to send pictures, which i did, and they would call me back, a week goes by and i call them, they tell me the tech looked at the pictures and declared that they are they right lines for a 71 truck axle but they say thats not the axle i have! It came out of a 71, it bolted up, codes on axle say 71, wtf. I know these line arent right and i feel like they dont care if they are or not. I told him the code numbers on the axle and told them to vrify it them selves. They then procceded to tell me the tech was out of town and they would call me monday, i will probably have to call them again. Any advice on getting them to correct this?
