which rag joint do I use with this steering box?

Answers

John
Speedway offers two versions of our new “800” series power steering gear box. 91032500 comes with a ¾” x 30 spline input shaft and 91032510 comes with 13/16” x 36 spline input shaft. Customer needs to order the correct rag joint or U-joint for the steering gear ordered. For an example if using on the 67-69 Camaro you would use part number 91032410 for the ¾” x 30 box and part # 91032414 for the 13/16” x 36 box.

I would not recommend having the box mounted on its side the warm gears need to be covered with fluid.

This 800 series steering box is heavier duty than the 605 steering box. Also the pitman arm spline is larger and will require a different pitman arm in order to use this box if you currently have a 605 box. The stock steering ratio's varied but most generally the two boxes are around a 16:1 rato.

This could very possibly be correct for your pickup. You will first need to measure the input shaft diameter and count the number of splines. These boxes were made with 3/4" - 30 spline as well as 13/16" - 36 spline. Determine your input shaft spline size and order appropriately.

I have a 1972 chevelle steering box in a 1955 Ford pickup and the input shaft is 11/16. I have measured it so many times and keep coming up with 11/16. The steering box part number is 7826692. I may be wrong, but I am having problems ordering U joints. If I am wrong I would like to know. Thank you.

The input shaft of GM 800 series boxes are either 3/4" x 30 spline or 13/16" x 36 spline. If you measure the OD of the spline and are coming up with 11/16" then you may want to try a different set of calipers or find a more precise tool. It is certainly possible that yours measures smaller than .750" but unlikely.
