Yeah I have been looking at steering box. I saw a few say the Borgeson box is not smaller. Then I have to think would I want to lift engine pull starter just to pull box when my car came with a close ratio steering box. This steering box unlike my 73 Duster is not the same thing I cant whip the wheel with my pinky it is much firmer than that. Is it worth it thinking a buddy of mine did a 70 Mustang coil overs and all went nuts. Quote its the same car I dont see a huge difference I wasted my money. I do think the manual brake cylinder is coming from DR Diff if I decide to order.
