1971 C10 2WD rear brake hard lines

[namredla]

Just out of curiosity, I am wondering if LMC gave me the wrong rear hard lines and wanted to tap into the knowledge of the forum for info. I ordered the pre-bent SS hard line set and new hoses. The order was correct for my 1971 C10 2WD 350 with rear coils. The only hitch is that it used to be a long bed but the frame was cut and it has a short bed now. I spent the holiday under the truck installing the new lines and made it all the way to the rear hardlines. Everything else fit perfectly. The two separate lines that run from the T at the end of the hose to the wheel cylinders were off. Firstly, they did not fit into the T, I had to buy an adapter nut (3/8 female to 7/16 male). That made the connections. The lines themselves seem too short as if they were made for the T to be on the top of the axle or otherwise not so far rotated to the front of the truck. It was TIGHT. But I was tired at that point and just made them fit. I called LMC but they had no clue what I was talking about and don't have the actual fitting information in front of them to help diagnose the issue. So, a couple of questions. One, does the long bed to short bed change cause me a problem somehow? I'm guessing not since the long line that runs in the frame rail down the passenger side fit just fine, and the hose was perfect. Two, did the 67-70's have the T fixed in a different location? A location where the hardlines would be a bit shorter than a 71?

Appreciate the help.
