7 1/4 tube length

The 8.75 in my Dart came from a 68 B body. I moved the spring hangars in equal amounts. The car had a 7.24 originally and there are no issues at all. Same story on the 8.75 in my 75 Duster. Chrysler never had a "short axle" like some fords. If that bothers you I can't wait to hear your opinion of the engine offset.... :)
