So, I borrowed my buddies welder and have been working on my 86 K30 project. I plan to use my stock 56" rear leaf pack reversed and inboarded so that the spring will be directly in line with the frame. Here is a picture of the front hanger I threw together tonight. For the shackle hanger I will use a shackle mount similar to what the front end of a Jeep with the front end shackle reversal. I will be shortening the wheelbase by at least 20". I will push the front axle forward 4-6". I'm shooting for around 115-120" wheelbase in the end. I also have a set of Ford 57" rears that will eventually find their way on the front.
