Will it fit thread

I’ve got no issues with rolling or cutting the fenders, but I’m hoping to stay with stock spring location.

Your demon is exactly what I picture, nice stuffed tire look.
The offset shackle kit is an easy deal. Hardest part is
rewelding spring pads which is simple for any welder.
Just do not get housing smoking hot (use wet rags) or it
may warp.

Next option: Calvert Racing makes a narrow one piece spring
that would increase clearance on tires. I used it on my duster year ago
for a few weeks even at the race track without adding his bars and
it worked great. It is a 10 Second small block race car (Hot Rod Project Car)
John asked me not to tell anyone how well the springs worked without his traction bars.
