67 has screw on cable -one year only speedo
67 has numbers radial (at angle)

68-69 has clip on cable
68-69 has numbers radial (at angle)

70-71 has clip on cable
70-71 has numbers horizontal

if you already have a 150 mph speedo, I would suggest you get it repaired and calibrated. call www.redlinegaugeworks.com

it’s very tough to confirm a used one is functioning perfect. And no telling when that 50 year old one will go bad too. Could be days after you install it, or years after.

While you are getting yours repaired you can choose to re-face the black and white background with original silkscreen process. Or leave your as-is. Your choice.

not correct

I edited my earlier post. Dave, could you review for future reference?

I kept seeing the numbers orientation change for 1970 on the overlay kits.

Edit: reading you post deeper it seems 1968 was a transition from early to late with cable type and number orientation.

Sorry, wrong. I'm not going to argue. That's like some people thinking that all S cars came with disc brakes.....wrong.
Go to Hamtramck and do your research.

Because all second gen Formula S Barracuda’s came with the 150 speedo

This is just info on the 150 speedo
1968 Barracuda, The 150 speedo can different ways. The number face is the same way as 1967. But the speedo end part of the speedo end came two different ways. Early 68 came with the screw on end and late came with the push on. As always with Chrysler I am sure some late ones also came with the crew on but I cannot prove that. I think some of The very late build 68 Barracuda built numbers on the face changed to the 69 style on the very late 68 cars built.

that make me possibly feel better about my 68 340-S. It has an SPD of Nov 14, 1967

It’s coded for 150 speedo and tach. And it has slanted speedo and tach numbers. And screw in cable.

always wondered if they were replaced.

can anyone verify the date codes on the back of my speedo?

BTW, My speedo was bouncing like mad and stopped. Redline Gaugeworks repaired it without needing parts. IIRC, lube and an adjustment. Then sprayed the face matte clear.

Apologies to 1500swinger and everyone else helping
me look for a 150 mph speedo for my 1968 Barracuda. I was completely wrong about the orientation of the numbers on my original. The speedometer numbers all read horizontal. The photo I posted before was one I pulled from the web and does NOT match mine. I am looking for the one with all horizontal numbers. Totally humbled and embarrased.

So the moderator says the thread has been moved to the discussion forum from the wanted classifieds.
Will repost another wanted ad in the wanted ads.

the one you posted is correct

At this point I am doubting just about everything I thought I knew about the second gen barracuda 150 mph speedo and if what is in my car is the original. Back to the drawing board for research

great post, lots of us are learning new thing too.

if it’s a mid to late car seems like it can be both ways.

What’s the SPD scheduled production date on your fender tag?

On bottom row of fender tag the SPD is group of 3 characters second group from right.

Fishing68 · May 29, 2021

So again thanks to everyone especially those with deep knowledge and willingness to chime in to correct my misconceptions. I will post my cars production date as soon as I get a chance to confirm what the fender tag has. (not going to get it wrong by relying on my proven faulty memory)

4spdragtop · May 29, 2021

No sweat, I apologize for sounding harsh. "Argue" wasnt the best choice of words I could have used. Great members on this site have "shown me the way" LOTS of times.

If autoxcuda's speedometer 332-6 is the date code that would translate to November 28, 1966.That date is approximately 3 months into the 1967 model year. Also this would explain the threaded cable. It's sometimes difficult to tell what's original on 50+ year old cars.

.......So again thanks to everyone especially those with deep knowledge and willingness to chime in to correct my misconceptions........

Some of us are seriously old geezers that have been around these cars since they were only a few years old, (like myself) of course there are always anomalies with these cars.

Side note, the burlwood almost looks like 67 style dash inlay?

For what it is worth, my 68 Barracuda, per the fender tag, built Oct of 1967, car did not have shoulder belts, it did have the roof shoulder belt mount, with out the welded in threaded nut, in place behind the head liner. That early ‘68 had a push on speedo connector.
Originally the car had a 120 mph speedometer , I bought a 150 speedo from a seller here on FABO. I had the speedo cleaned and re conditioned at Deluxe Speedometer in Denver CO. As delicate as the magnets and mechanical drive system is in those antique gauges, I would have even a NOS speedo professionally inspected and cleaned prior to installation.

What does it cost to have a speedo reconditioned?

RedFish · May 29, 2021

1968 was not only a transition year for several changes but there was a railroad strike causing parts shortages too. Some number of Valiants were built with the B'cuda dash that year. Parts shortage or not, they always used up inventory on hand before implementing changes. A early 68 model could have the burlwood overlay ( only cut out different/larger at the fan switch ), Speedometer with screw on cable, Reverse lamp switch still inside the cab, etc...

My fender tag on my 1968 Barracuda shows the bottom line BH 52 5 39 A19 ......
If I understand correctly the A19 translates to a build date of October 19th.
The speedometer in the car is the push on cable type with the horizontal reading numbers on the face. I had assumed it was original to the car. Since it sounds like 1968 was a transition year for speedometer design does anyone want to weigh in on the chance the speedo I have in the car could be original?

Thanks for reaching out 1500Swinger. -I don't know if that one is the same. I think there are variations depending on year, at least before 1967... so I am interested but not sure of yours is a match. Do you have a photo? I know the 1968 has the non upright numbers and a push on style cable attachment in back.

NOT SO , MY 68 FORM S HAS A 120 MPH SPEEDOMETER , WITH A SCREW ON CABLE -----------JFYI

MINE HAS DONE THE SAME THING . What did it cost you ?

I traded some parts. And that was 7 years ago.

Just call them and ask for a speedo tune-up and inspection.

The bigger cost is the refacing with the silkscreen of the face. They have to remove the face, remove paint & numbers, paint it black, new silkscreen it, re-attach it to speedo, re-paint & install pointer. Quite a bit of labor.

my cutout fits the 68 dash fascia.

notice my tach has slanted numbers? Is that a 67-early 68 model year thing?
