let the sway bar sit on top of the pins, and see if it lines up ok, mark it all up, and chop it, then get the oxy out and just bash the ends kinda flat, then just drill em. i dont think it wil need heat treating coz it should be spring steel.
can u move ur sway bar brackets forward at all? what about making new pins up? that will come out like and up side down L but with a cross bracket for strength? in the shape of a triangle?
or of course, getting a custom sway bar,thats what i'd be doing if those ideas dont work.then u know its fine. and u will have no issues.
