radiator transmission lines help
6602, 6701, 7001 - they should all work about the same. The 6701, for example, covers (really) small to BB applications. They basically come out of the same point on the tranny's and go to the same point at the bottom of the radiator. The bends between those two points will vary but you're not doing a factory resto and that's what those lines are designed to duplicate. Even your aftermarket downflow radiator will have cooler fittings located very close to the factory.
There are tight bends that come out of the tranny fittings, some weird bends in the bellhousing area, and then it's a straight shot forward along the oil pan rail before they bend left and right to line up with the radiator fittings. In your case you just need to find the best match (since 440's didn't come in 71 Darts) and make slight mods as needed. A '69 BB Dart (RTC6602) appears to be the best match.
Then, you just need flare fittings to match the lines on one end and the pipe fitting holes on the rad. A decent auto parts store should have them.
