@Voetom I recently had a full new exhaust system installed on my Coronet. Changed to HIPO manifolds with full 2-1/2 to 2-1/4 pipes with turndowns and Flowmaster Delta 50 mufflers. We used factory-style brackets at rear of mufflers and tailpipes. The previous mufflers were Flowmaster Delta...
I believe they were this style acorn nut. As AR67GTX said, they are often stripped though.

Can anyone identify the factory correct mounting location for the Cleaner Air Package(CAP) timing control valve on a 1967 Coronet 383 4 barrel? When I got the car, it was mounted on the right side intake manifold, second bolt from the back. I can’t find any information online or in the FSM...
I just checked eBay, looks like there are a few available for your car, but if you want to go the rebuild route, this guy did mine a few years ago and did a great job. Not sure if he’s still doing them, but worth a try:

I’ve searched forums, but did not find an answer to this question.
67 Coronet, 383. Engine rebuild is nearing completion. I am replacing the full exhaust system at the same time. I am replacing the original log-style manifolds with 68-69 HP manifolds P/N’s 2843992 and 2806900. It appears...
If you are looking for the original part number for your gas cap, it is 2643998.

One thing to note on the repops for the 67 Coronet - the strip directly below the speedometer is chromed on the repops. The original bezels are black. I never understood how this was missed in design/manufacturing. It may not matter to some, but it is not correct.
You need to grind the welds that attach the shaft to the butterfly valve. This will release the shaft so that it can slide out.
The new valve will need to be welded to the new shaft.

I can’t speak specifically to the GTX, but I have had the instrument panel out of my 67 Coronet with A/C numerous times. I found it best to remove the A/C duct from the driver’s A/C vent first. There are two screws holding the A/C vent to the lower dash. Remove the screw closest to the...
I think your main issue is that you do not have the vacuum harness attached to your heater box (as stated in post #6). That harness has vacuum lines that attach to each diaphragm on the box and runs to the A/C switch on the dash and provides the vacuum line that would run to the intake...
The main vacuum for the system runs via vacuum line from a fitting on the left rear of the intake manifold directly to a port on the A/C switch in the dash. The FSM has lots of diagrams to illustrate the vacuum line routing. Here’s an example from my ‘67 manual, but there are differences in...
Not sure about the speaker size for your specific application, but check out the bottom two pictures in post 14 of the thread below. Two small (3-1/2”) coaxial speakers mounted to a single plate to fit in the location of your center speaker. I made my own, but they are available for some...
