Well the swap is done. I have 57's in the fron with an 80* to 90* shackle angle and the rear has a 65* shackle angle. 7" eye to eye shackles up front (DIY4X great product), stock rear 88-98 shackles. The rear mount is all the way at the rear of the frame did not touch the front mount for the rear springs. Front mount for front springs is swapped side to side (this was a pain in the a$$ b/c my truck had apparently been in an accident and we had to straighten the frame on the passenger side to make the brackets work) the rear hanger for the front springs was not touched. I need to brace the front and rear of my frame and we will see from there. I am going to flex it today and I will post pics tommorrow.
