69 Dart Heater Hose Length

I need to get some heater hose for my 69 Dart which was originally a slant six but now has a 400 big block. Unfortunately, when I pulled the slant I didn't save the old hoses to use to get a measurement for new hose. I am adding the fender hose support bracket that the big block Darts came with and would like to ask if someone with a big block 69 A-body can tell me what the combined length of the two hoses is so I know how much to get at the auto parts store. I tried mocking it up using an extension cord but it is not rigid enough to hold in place to get an accurate measurement.
