They work and fit great . At least they did in my Barracuda. Remember that you can mix and match engine mounts to get more clearance where needed ... at least you can on the older pre spool mounts.
they sure do fit good. Would go so far as to say they fit better than any A body header i have ever had. Definitely fit better than the TTI step, had those on a 416 in a Duster years ago. My 1 7/8 W5 TTI’s actually fit better than those step headers did on eddie heads
