Hi Dennis, I'm glad to assist you. Our supplier Dorman brand does not show those specifications since this is a direct fit part matching the OEM part number 2290000 or 7826542. This is for manual steering. For us to accurately identify the correct part for your vehicle, please provide your complete vehicle information (year, make, model, submodel, and engine size). Once you enter your vehicle application online, a green round badge with a white checkmark would show up confirming 100% fitment. If good. Grab our discounted sale price offer and click the link below to order today. I hope this helps. Happy shopping. https://www.carparts.com/steering-coupling/dorman/rb31011?can=CPJE1043_20220331

Hi, To check the fitment of this part please use our Vehicle Selector — which can be found towards the top of the homepage as well as all categories, search results, and product pages — can help verify if a part will fit your specific application. To enter your application, simply select your vehicle’s year, make, model, sub-model, and engine type and click “Go.” Once your application is selected, you’ll see a “Guaranteed to Fit” badge if the part will fit, and we recommend that you also double-check Your Vehicle Fit Details as well as the Vehicle Fitment Information table on the product page.
