"Restoration" was a general term. A "mild custom" would be a more appropriate term. It basically looks stock on the outside, but my customer wanted the modern conveniences of power steering and power brakes. In addition, he wanted taller rear end gears (3.38:1) with the stock 4-speed transmission. I'm not sure why there is such a disparity in the speedo reading (probably the rear end gears), as the wheels and tires are not that much different than the originals. The power brake booster is the unit that Classic Performance Products sells that mounts right on the stock master cylinder bracket on the frame. Problem is the booster is too close to where the speedo cable attaches to the transmission. The problem can be solved by moving the master cylinder and booster assembly further rearward, but this is a major project that I would rather not perform unless there is an alternate solution.
