Not a problem! I mean, I swear I've looked at every variant for A bodies in the last week, so I know how confusing it can be, especially when some sites list several options for each car and they are all a little different from each other. I can't believe there was that much difference between 318, 340, and 360, all with the same pump but had different hose numbers. I picked one that was most common and we will see what happens.
All that being said, there's a place in pass every day I go to work that makes custom hydraulic hoses, and I'm thinking that for the other Dart I'm going to mock up a hose template and have them make one that suits my needs. I'll just have to make sure to account for engine movement and stuff first.
