Steel Braid Rear Brake Line

I have to get a new rear flexible brake line for the bus. I noticed that after i installed the new rear axle, the brake line is almost fully extended at ride height. This is not good. So I need a new rear line. Fortunately i am still using the original brass junction that bolts to the diff housing. So where is a good palce to purchase the lines from that i can get some kind of technical support from the people because i want to make sure the line and adapters will fit what i have. Or does somebody have a part nubmer for the 3/16 to AN adapters for the frame to flex line and the adapter nubmer for the line to brass junction on the pumkin.

 

Thanks Mike, i will prolbably give them a call. Anyone know what size the fitting is on the rear rubber line that screws into the brass junction block on the axle? I was looknig at the catalog and got everything else in mind but i want to see if somebody has the size so i do not have to open up the brake lines
