Will this fit with a column shifter th350?CraigFeb 23, 2021
Best Answer:Hi Craig, To check the fitment 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.

Customer Reviews

Long Tube Headers
I had ordered these parts for my husband. He was so happy and he's commented several times on the speed /fast shipping your company provides. He got the order within a few day, at no cost as parts qualified for free shipping. The parts were just as pictured and they fit perfect. He commented he didn't have to make any adjustments, which made his job a lot easier. Thank you so much for not only shipping, but for all the personnel you have. It is appreciated.
