BJ7 vs BT7?

I posted a similar question under the brake pipes steel or ss post, as I was looking for blue prints for pipes.

What I'd really like to know is does anyone know the detail of all of the differences between a BT7 and a BJ7?
 
I'm working on the brake and fuel pipes. Classic Tube has blue prints for a BT7. I have an AH restoration guide that says that there is very little difference between a BT7 and a BJ7. Are the brake and fuel lines identical?
 
I have a BT-7 and can't comment on the difference between that car and a BJ7 on the brake line issue. However, having worked on both the 2 carb (BJ8, which I assume is very similar to a BJ7's engine compartment fuel lines) and BT7 tri carb fuel components, there is a difference in the length of fuel lines, specifically the length of the line from the fuel feed in the engine compartment to the first carb. Just a minor Petrofelx line difference (or rubber if you like). Can't think of anything else in the fuel arena, except for the obvious differences in carbs, etc.
 
The fuel lines are slightly different. I think that the BT7 will have a slightly longer line coming up into the engine compartment to meet the petroflex. The brake lines are identical.
 
OK, great! I'm all set with the brakes line then. Thanks fellas!

Would anyone have BJ7 pics and/or measurements of the fuel lines? I'm thinking of the fuel pump and connections and then where the line ends near the carbs. I can make up a template with string and wire for the bend techs. But I don't know exactly where to end and what fittings should be there. I should have mentioned that I have no fuel pump. The only one that I had (years ago) was a cheap aftermarket with rubber hoses. As I understand it all fuel lines in the rear are steel, no hose.
