I have a set of early 260 bumpers that are in pretty good shape; I have removed my stock 1977 280’s some time ago. Does a direct-fit early 260 to late 280 conversion bracket exist? Any trusted Z sources that would fabricate? Looking for brackets that will bolt up to stock mounts on 260 bumper and will attach to 280 body at the single threaded body mounts. All the conversions I have found take 240 bumpers to a 280 w/“some modification/fabrication/bend or weld”. I believe the early 74 260 bumpers were moved outward from the body compared to 240’s so wouldn’t this require a (longer) bracket just for the 260? If so, has anyone used-does anyone know of using- a 260 bracket and mounting it to a late 280? Would it match up to a 280’s body without drilling new body mounting”holes”? I am at a stop sign and need help🙏 Anyone do this....or know how, who or where?? Thanks!!!
