actually they make a front hanger to allow it to work.
andyf makes them I think and firm feel sells them.
I have a set on my car to use ebody springs.

I suppose you could redrill your hangers to push the hole out 1 inch if there is enough meat.
I assume we're talking a 66-70 B body here... If that is the case, I don't understand how that could work, if you adjusted for it in the front hanger you would be moving the wheels back 1 inch. Do you have a link for these hangers?
OP there are kits to move your shackles forward 1 inch that are designed for using an A body S/S spring on a B body. This kit would do what you need and allow you to run the E body spring, but it requires cutting and welding. I'd suggest that you just get some B body springs.
