I don't use a cell phone, I'll contact you back asap. I bought these from an estate thinking I might use them or at least see if they would fit something I have. The guy did have an early bronco with manifolds on it, so I assume that's what these were for, but he did have a lot of vehicles, it's just a guess. Comes with collectors. Ends have some rust damage. Never mounted on an engine. I didn't see a brand or any markings on them. Not sure what transmission they all fit. sbf 289 302 I usually only check email once a day but not on weekends. Cash only.
