Need some help from you short bed guys!!!

[Classic Heartbeat]

Now I have worked on enough trucks to know that a Blazer has a 104" wheelbase, a short bed has a 115" wheel base, and a long bed has a 127" wheelbase and Longhorn has a 133" wheelbase.
My dilemma is, I ordered a 67-70 Disk Brake Conversion Brake Line set from IN-Line Tube for a 68 GMC short bed truck. The intermediate brake line in the kit they sent me is 92" from the front of the line to where the bend is in the rear. That my friends is about 11" too short!!!
As you guys know, I have a Blazer in the shop, and a shortbed truck in the shop. I have measured the lines on both vehicles and the Blazer has a 92" line and the short box has a 113" line (give or take because of bends in the frame)
In-line tube is trying to tell me that the 92" line is correct for the short bed and have dug their heels in! They say that they sell that kit to all of the major catolog companies and haven't had a single complaint! That the brake line that came out of the GMC isn't an original, or if it is they don't have it in the books.
You guys know that a shot bed is a short bed! All 67-72s have the same wheelbase and have a single piece line that goes from the front end to the rear end!

So now what I need from you short bed guys is to measure your factory brake line that runs down the frame. Just the strait section from the front of the line to the bend in the rear and respond in this thread what measurement you came up with.

In-Line tube says that if I send the original line to them that they will duplicate it at no expence to us or my customer. However the catch is we have to ship it to them at our expence. Not realy a big deal unless you are someone who stands on their principals. Their line is wrong and that is that!! I, or my customer shouldn't have to eat any expence because of that!! I told them I would box up the line and they could issue a call tag if they wanted the sample, they declined. I gave them the new measurement with pictures and said just make a new line and they declined again! I told them that their line is flat wrong!! And they say that nobody else is complaining!!
Well lets start complaining!!
You guys as well as I want the best quality parts and we want them right!

So please take the measurement and reply with your demention in this thread. (you can call them toll free with your demention to 800-385-9452 and talk to customer service) This isn't just for my customer and I, it is for all of us who want our parts correct. If you are someone who has purchased a short bed kit from In-Line tube could you please chime in too. Especialy if you had to add a section to their line to make it work. Together we might just get this resolved!
Sorry for the long post, WES
