The SFEH is in the factory location.
The front hanger was installed according to dimensions we have found work well for appropriate shackle angles taking into account the weight of the engine. From the SFEH forward the front spring eye bolt is 51.25".
While technically the hanger is not in the factory location, and if I weren't using a Dodge 52, the axle would be "relatively" in the factory location.
The rear spring front hanger is in the factory location.
I built the shackle flip this evening and intend on installing that tomorrow. The shackle flip is a bit different than our standard offering. Of course its a weld on and due to the fact I don't have a fixed location on the frame to work around determined by a bolt pattern, I built it with a centered bushing. It will be applied to the frame correcting the shackle angle at the same time. 1" further forward than the stock pivot point would normally be. Same as is true with our standard shackle flip.
So far, everything is coming together pretty smoothly. I am thouroughly enjoying the fact that the Generals influence has been largely removed from my build process. At the same time, drawing from the experience of the years spent with the Chevy frames. There are alot of things that could be done differently if a person wanted to. I find when thinking things through some mods while solving one issue could easily develop several issues regarding something else nearby. Alot of things i've considered doing differently have been shelved for this very reason. It'd be real easy to dig yourself into a hole and cause a lot of rework if you're not careful what changes are made.
