69 Dart Heater Hose Length

[69GT]

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.

How about using something like the wire from a coat hanger ? Might not be long enough but something like that. Can't be that expensive, just go get 6 feet or a little more.
