This is my third attempt to buy one of these aftermarket ignition lock cylinders. Even though there are different venders selling them, the cores all appear to come from the same manufacture. The big issue is that you can turn the locks with ANY key. I can turn them with blank keys, different keys, my original car keys so they are not secure at all (does NOT matter what car you install them in). The tumblers in the OEM cylinder stick out more making it work much better than these aftermarket cores. I ended up having to go with the next generation FORD lock cylinder (https://www.amazon.com/gp/product/B000IYIUGO/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) for the 96 and up F150's which is a redesign but way more secure and works in the 95 F150's. The only downside to doing this is that you can't turn the key backwards for ACC which I never use anyways.
