Exhaust hanger location. 69 a-body

I used Accurate headpipes and mufflers on my 68 383 Dart GTS with NOS tailpipes. I had to use reducers on the outlets of the mufflers so the little tiny factory tailpipes could be used. The rest of the Accurate system was nice, but if you buy where the headpipes are shipped to you then you get two pieces. If you buy in advance and have Tom bring them to you at a show then you can get them in one piece.

Don't have measurements, but you can see where the bracket is in relation to the seat belt anchor.

Here is the left side:



and here is the right side:

Can't quite tell, but your photo seems to show 3 large holes and 2 small holes. My 69 Barracuda has 3 large holes but only one small screw hole to mount the "plate assembly" inside the car. See the plate assembly at 69 Plymouth FSM, page 11-4, fig. 3, view E.

Maybe you are missing the R side exhaust hanger bracket that goes under the car and the plate assemply that goes inside the car with 3 bolts to fasten the bracket to the floor pan?

Here's a photo of my unmolested 69 Barracuda. I ordered the car in the fall of 1968.

Here's a photo of the bare metal plate assembly that goes inside the car. The 3 bolts are round flat head machine screws 1/4-20 x 9/16 spot welded to the plate. The hole in the center of the plate is for a Phillips pan head tapping screw #10-12 x 1/2, zinc plated.

The plate and bolt heads are hidden behind the back seat, so hex head machine screws could be used. If you need to make a plate assembly, it is simply sheet steel 0.056" thick with 2 bends. PM me for a drawing or more details.

This bare metal R side exhaust hanger bracket is available as a reproduction item from somebody. It mounts to the plate assembly with 3 Keps nuts, conical, same as B-11479, shown on page 52 at:

A J-nut fits in the square hole and is 5/16-18, similar to B-11516, page 58 at the link above.
