Car came with the front end as is, as near as I can tell it's an early 1980's Mustang II front end. manual rack/pinion. All I did with it was add adjustable coil overs and replaced all the bushings. My buddy, a shade-tree mechanic, races a Mustang with the same front end set up, just larger discs, so he was familiar with it. After which, the last thing done was to replace the manual brakes with power. It did not do this until after my buddy & I replaced the manual brake system with power booster/dual master...
Classic case of "don't fix it if it's not broken"?
