62 Lancer Vs 68 Dart

I have spindles and discs from a 71 Dart on my Valiant 1962 and it works just fine. But thats the only thing that is the same from the 62-66. all the rest i diffrent. I suggest that you do the same that I´m going to do with my new Project.
A 1961 Valiant with the whole front end from a Dart Swinger 1974. I going to wide the frame and change the torsion cross member so it will be more space and I get a more relably K-frame for my +500hp 5.9 Magnum :D
