Firm Feel is a great resource if you want your original box rebuilt.
PST is a site sponsor and gives a discount, they sell reproduction steering boxes that look like the originals. They offer them in the standard factory 24:1 (5 1/2 turns lock to lock), a quickened 20:1 (4 1/2 turns lock to lock), and the factory "fast ratio" 16:1 (3 1/2 turns lock to lock).
The flaming river manual boxes are 16:1 and have a steel case, so they're a bit heavier than the factory aluminum version.
