i have a 69 dart im building,and it came with a moiser d60 rear,narrowed,all done ready to go,w/ disc's..so i already removed the inners to do a minitub,and the rear end was narrowed to use with the springs to be mounted in the framerail. i see mancini has the kits for sale to do this. what i was wondering can i have some tips on installing the kit??? i have never installed one of these,so i was hoping you all would give me some do's,and dont's on the install....thanks guys..mike
