Im building a 79 CJ5. Currently it has a ford 5.0, T-5 tranny, Dana 300, Dana 70 rear, looking for a dana 60 front. As far as springs, they are stock with a spring over and buggy springs. I'v done the shackle reversal in the front and stretched the wheelbase 7". The question I have is about the springs themselves. I have read in several articles about rockcrawlers with high flex leaf springs. Im curious about these springs and would appreciate any imput about them and where or who builds them.
