First.. guess I decided to have a little garage day all by myself after work this evening. I get lots done at night when the little lady works a closing shift (dont see her until 10pm). Started off by dropping the old rear axle & springs. Then I fired up the torch. 26 rivets and one BFH later (5 on the other side) I got all the brackets on the drivers side off. Decided to mock up where I've been planning to put the new hangers. Front is just where I wanted it, except there will be a 1" spacer added between the frame rail and lower bracket, this will lower the whole bracket 1", lining up the top of the bracket with the top of the frame. I'm thinking I need to move the rear hanger forward a little bit for more angle. Springs are chevy 56", long side forward. no weight on spring (obviously), also no hanging weight other than the spring itself. 6" shackle. This is making me consider not finalizing the rear hanger position until MUCH later on in the build process when I can mock it up with weight on it. New rear suspension mocked up on the drivers side. Axle location ended up right where I where I wanted it (right where it was before). Front hanger. Moved forward 4" from existing location. Conveniently there were 2 holes, both 4" forward of existing holes to attach the lower bracket to. This is where the 1" spacer will be, between the bottom of the frame, and the lower bracket. Frame is not sitting level in this picture. Shackle angle is almost perfectly vertical. Mount point for the top of the shackle is moved forward approx 1" from stock. Tilted camera to picture as if the frame was level. I think the hanger needs to move forward another inch at least.
