66-67 B body tail pipe hangars

How do the rear most tail pipe hangars on a 67 b-body with a hemi attach to the frame?? I see a square and round hole in that vicinity in the frame but don`t have the hangers yet. Just ordered a complete system from Accurate Exhaust and Im trying to make sure I am ready when it arrives. these round holes are not threaded nor do they have a nut attached on the top side.

thanks.

Usually the square or rectangular hole is for a locating tab, with the round hole being for the fastener. Pretty sure the fastener would be 5/16-18 thread, likely self-tapping if there's no nut welded inside the rail, but if you see what looks like a square plate behind/inside of that hole, that's for a self-tapping bolt.
I have a pair of tailpipe hangers for a'67 GTX; don't know if they're the same for Hemis & 440s.

My car has j bolts in the frame and 5/16 bolts going straight up into them.

Beautiful car!!. What do you mean by J bolts?? Are you talking about the kind that slide over the hole and have a threaded attachment like what you see on fenders and body parts??

Maybe someone can pOst a detail from the service manual? If the attaching nut is not welded on the inside if the side of the frame it may be on the bottom if the frame. I don'thave a67 but my tip hanger hooks into the hole in the side of the frame and the bolt screws into a threaded insert in the bottom if the frame. It will be pretty obvious when you get your parts

yes same type of fastener as a fender.

Tom, is that for the tailpipe tip or the muffler?
