    Do you have the dimensions from the gearbox mounting bolts to the top of the gearbox with hoses installed? I have an aftermarket brake booster and master cylinder and I want to make sure I have clearance.

    Kit #999020 is a complete kit for a small block car with factory manual steering. Kit #999023 is a complete kit for small block cars with factory power steering. Both kits are hydraulic and not electric.

    I’ve installed this kit and I’m going to purchase headers. Im running a 302 and AOD transmission. Will long tube headers work for this? Can I use a Saginaw style pump with this kit?

    You can use a Saginaw pump with this kit, to use it with the included hoses you will need an adapter #925123. Long tube headers generally offer the best fitment and clearance with our steering box.

    Will this whole kit fit a 1965 Ford Falcon Ranchero? If not, which parts will/will not?

    For a 1965 Falcon we will need to know the diameter of the pitman shaft. The Falcon used both 1” and 1-1/8 diameter shafts. You need to measure the diameter at the top of the spline near the casting as it is tapered. If the arm is still installed you can alternatively measure the diameter of the threads on the bottom of the shaft. 1” Diameter boxes have a 3/4” thread and 1-1/8” boxes have a 7/8” thread. We offer the 1” diameter, part #800110 and 1-1/8” diameter, part #800111 power steering conversion boxes. Additionally, the steering column will need to be shortened for installation of our box. This makes installation with a column shift very difficult.
